This PR contains the first implementation of `cached_shape!` macro, which should help us with reducing draw calls in our application.
```rust
mod icon1 {
use super::*;
ensogl_core::cached_shape! { 32 x 32;
() {
let shape = Circle(16.px()).fill(color::Rgba::green());
shape.into()
}
}
}
mod icon2 {
use super::*;
ensogl_core::cached_shape! { 202 x 312;
() {
let shape = Rect((200.px(), 310.px())).fill(color::Rgba::red());
shape.into()
}
}
}
```
The above code creates two cached shapes. They are similar to normal shapes (created with `shape!` macro), except that:
1. they do not allow for any parametrization
2. They are rendered at the application start to the special texture with cached shapes.
The texture will be used in next PRs to cache all Component Browser icons on the texture and draw all of them just by single, fast draw call. In the future, more shapes can be cached, further reducing draw calls and making them simple.
# Important Notes
The results are presented in `cached_shapes` debug scene: there are two shapes displayed and a scaled cached texture is displayed in the background.
This PR implements HTML generation from documentation IR for all suggestion database entries and replaces the old documentation panel with a newer one.
Additional adjustments to the looks of the documentation would be applied separately in a future PR. This PR focuses on the fastest possible delivery of a usable documentation panel. We want to test it in real-world use cases and gather feedback for future improvements.

# Important Notes
- Fixed language protocol data structures.
- Scrolling to the selected method is also implemented here.
- Also, the selected item is highlighted with yellow.
- Only some pieces of information we have are displayed. For example, we don't display return types for methods or types of arguments.
- A bunch of code related to previous implementation is removed, but probably not all of it.

# Important Notes
* the best laziness is used for `Text` type, which makes use of its internal representation to send data
* any type will first compute its default string representation and then send the content of that lazy to the IDE
* special handling of files and their content will be implemented in the future
* size of the displayed text can be updated dynamically based on best effort information: if the backend does not yet know the full width/height of the text, it can update the IDE at any time and this will be handled gracefully by updating the scrollbar position and sizes.
This is a followup to https://github.com/enso-org/enso/pull/4046#pullrequestreview-1248164069.
- Compiler job cancelation is now handled - the cache entry will be cleared or the job will be resumed if there is still demand.
- The compilation awaiting process has been rewritten to not use polling. The "read cache" job is now only used to dispatch known valid reads. It is always completed within a single run cycle.
- Changed shader struct to use `ImString` for storing code, so it can be cheaply cloned. This is now common, as we are cloning it from cache.
`@` should not be legal to use as a binary operator. I accepted it in the parser because it occurred in the .enso sources, but it was actually used to create a syntax error to test error recovery.
See: https://www.pivotaltracker.com/story/show/184054024
The fix consists of two parts:
1. All the "review-apply" and "store temporary md" actions in the searcher controller are now guarded by an ignored transaction.
2. Because some of the temporary state may reach the UR frames assigned to other actions, added a bunch of code for removing all temporary expressions from the code and use it after restoring a frame. We may consider using it after project load as well.
### Important Notes
Added a useful method "log_err" to ResultOps (so every Result will have those).
Logging: Replace tracing with an efficient logging implementation, with 0-runtime cost for disabled log levels. (https://www.pivotaltracker.com/story/show/183755412)
Profiling: Support submitting `profiler` events to the User Timing Web API, so that measurements can be viewed directly in the browser. (https://www.pivotaltracker.com/story/show/184003550)
# Important Notes
Logging interface:
- The macros (`warn!`, etc.) now take standard `format_args!` arguments (the tracing implementations accepted a broader syntax).
- Compile-time log levels can now be set through the CLI, like so:
`./run ide start --log-level=trace --uncollapsed-log-level=info`
Profiling:
- The hotkey Ctrl+Alt+Shift+P submits all `profiler` events logged since the application was loaded to the Web API, so that they can then be viewed with the browser's developer tools. Note that standard tools are not able to represent async task lifetimes or metadata; this is a convenient interface to a subset of `profiler` data.
- As an alternative interface, a runtime flag enables continuous measurement submission. In the browser it can be set through a URL parameter, like http://localhost:8080/?emit_user_timing_measurements=true. Note that this mode significantly impacts performance.

Reduced impact of node dropdown widgets on load times by deferring creation of grid views until each widget is opened. This also improves node editing time, as the dropdowns are not recreated immediately.
This approach of lazy initialization now caused a significant lag when opening the dropdown. Two major causes of the lag spike is glyph generation (msdfgen, `new_glyph`) and shader compilation (happened every time, because each dropdown has unique layer stack). To reduce the impact of that, the shader compiler now caches the shaders based on generated shader source. Glyph creation hasn't been changed and is still slow. The startup performance is now roughly where it was before introducing widgets.

This PR implements Intermediate Representation for our documentation. Later these data structures would be used to generate HTML and CSS for the documentation panel. For now, we display it in the debug scene.

# Important Notes
- `suggestion-database` now lives in a separate crate
- also, two utility crates were introduced for the `notification` and `executor` modules of enso-gui
- documentation debug scene is moved to a separate crate
- All refactorings are done in the last two commits

Added a dropdown widget to graph node for all span tree nodes that have tag values present. When an option is selected, the controller receives a partial expression update, which targets specific crumbs of the expression (similar to how edge endpoint updates work).
https://user-images.githubusercontent.com/919491/210219931-8ae418fd-3ac4-44a5-abea-9e670f15cdf9.mp4
# Important Notes
Right now the dropdown widget is recreated every time the node is edited, including a dropdown option being selected. This causes it to close every time. I wanted to get around that by diffing span trees, but I wasn't able to do it in useful way. Additionally, current implementation of node input expression view heavily relies on being reinitialized from scratch every time. This led to more necessary changes than I was comfortable with for this task. I believe it will be easier to implement it as part of more complete widget support, especially after dynamic data support, as we will have proper widget type information.
Implements https://www.pivotaltracker.com/n/projects/2539304/stories/184023380
Dropdown component. Planned to be used in nodes as a single and multiple selection widget, both for static and dynamically loaded values. Initial support is focused on static data, with limited support for dynamic sources. Notably, loading states are not supported yet. Full support for that is planned to be added later with widget lazy-loading.
- Supports single and multiple selections.
- Dedicated API for providing a static list of all entries.
- Range-based query API for dynamically loading data as it is scrolled (only basic support - will need more work for proper async lazy-loading).
- Internal entry cache and query batching to avoid querying data one by one (the batching for now is very basic, will have to be improved for proper lazy-loading).
- Automatic dropdown width adjustment based on the entry label lengths, up to a set max allowed value.
- Open and close animation.
- Keyboard support for focusing and selecting entries.
# Important Notes
Implementing the dropdown on top of grid-view have uncovered some assumptions around grid-view layers. It was assumed to always be a part of the component browser. Removing that assumption required a mechanism for propagating camera update information through layer tree. This is now implemented using a `camera_parent` layer field. Ideally each layer should simply have at most a single parent, and camera inheritance would follow that. That refactor turned out to be quite involved, so right now the simpler temporary solution is introduced in order to not delay this PR further.
This PR provides a visual indication of whether the project's current state differs from the most recent snapshot saved in the VCS. The project name displayed in the IDE changes to a darker text to indicate that the VCS snapshot is outdated, and back to a lighter text when the current project state corresponds to the last saved VCS snapshot.
https://user-images.githubusercontent.com/117099775/208088438-20dfc2aa-2a7d-47bf-bc12-3d3dff7a4974.mp4
The outdated project snapshot indicator is set when:
* A node is moved.
* A node is added or removed.
* The text editor is used to edit the text.
* The project is auto-saved, and the auto-saved project state does not correspond to the last saved snapshot in the VCS.
The outdated project snapshot indicator is cleared when:
* A new project snapshot is successfully saved using `ctrl+s`.
* The project is auto-saved, and the auto-saved project state is confirmed to correspond to the last saved snapshot in the VCS. This occurs, for example, when a project change is undone and the project is reverted to the last saved snapshot state.
The auto-save events do not occur immediately after a project change but have a short delay, thus the VCS status update is affected by the same delay when triggered by an auto-save event.
This is an enhancement of the `Slider` component implemented in #3852. It adds the following features:
* Tooltips and precision change hints
* Selectable slider limit behaviors
* Textual slider value editing
* Vertical slider layout
#### Tooltips
An information tooltip can now be added to a slider, it is shown when the mouse hovers over the component. Additionally, a pop-up indicating the slider's precision appears when the slider's precision has been adjusted.
https://user-images.githubusercontent.com/117099775/206148098-3b4dc059-18aa-4200-9ee0-5d4382363810.mp4
#### Slider limits
The previous slider implementation clamped the adjusted value to the slider's minimum/maximum limits. Now the following behaviors are available:
* Hard limits: Clamp the value to a range within the slider's limits.
* Soft limits: The value can extend beyond the slider's limits. When this occurs, an overflow indicator will be displayed on the side of the limit that is exceeded.
* Adaptive limits: The value can extend beyond the slider's limits. When this occurs, the exceeded limit will temporarily be adjusted to double the slider's range. This will be performed iteratively until the value falls within the extended limits. When a limit is extended and the value is adjusted to fit a smaller range, the extended limit will be iteratively halved until only the necessary range is covered. The slider's extended limits will never shrink to a range smaller than the original range.
These behaviors can be set to the lower and upper limits of a slider independently.

#### Textual editing
The slider's value can now be entered through a text input field. Double-click to edit the slider's current value. To confirm the edit press `enter`, or press `escape` to cancel the edit. If an invalid value is entered on confirmation the slider will revert to its value before the edit. The slider's precision will be adjusted based on the number of decimal places of the value entered.
https://user-images.githubusercontent.com/117099775/206148170-d3fa4c82-6e73-4b1c-9be9-cb99979f7b70.mp4
#### Vertical layout
The slider component now supports a vertical layout. In this case value adjustment is performed by a vertical mouse movement, and a horizontal movement adjusts the slider's precision. The slider's track now fills the component in a vertical direction, and the slider's label is displayed near the top end of the component.
https://user-images.githubusercontent.com/117099775/206148211-0f176aaf-bc1b-45e2-afd7-0d28391aafcb.mp4
#### Scroll bar mode
The slider component supports two indicator modes:
* `Track`: The component is filled with a colored bar from the lower limit (empty) to the upper limit (full) dependent on the slider's value.
* `Thumb`: The component contains a rounded indicator that moves along the slider from one end to the other, indicating the slider's value proportionally to the slider's limits. The width of the indicator is configurable.
In addition, the value text, text entry, and precision adjustment can be turned off to provide a scroll bar appearance when used with the `Thumb` indicator.

#### Example scene shortcuts
The example scene contains two shortcuts in order to evaluate the dynamic addition and removal of the slider components:
* `CTRL+D` drops all the slider components that are added to the scene.
* `CTRL+A` adds a new set of example slider components to the scene.

# Important Notes
The root cause of the issue was a missing deref before `flavor()` call. The autoderef doesn't work there, because the `ShapeSystemFlavorProvider` trait is implemented for all types, including `Ref`. We should reconsider if blanket default impl is a good idea, as this is a very scary footgun.
Apart from that, the cleanup of layer elements was not handling systems with same ID but different flavors correctly. That could cause text to disappear when given layer had text of multiple fonts, and all shapes of one of them got removed. Now the element is removed from layer only when all systems sharing given system ID have no more instances to render.
This PR is a draft PR while I learn EnsoGL. The eventual goal is to implement the projects list portion of the cloud dashboard in this PR. This PR will implement part of https://www.pivotaltracker.com/n/projects/2539513/stories/183557950
### Important Notes
This PR is still really rough and contains a lot of hacks & hard-coded values. The FRP usage is also likely to be suboptimal and need fixing.
Fix issues noted here: https://github.com/enso-org/enso/pull/3678#issuecomment-1273623924
- Time complexity of an operation during line-redrawing scaled quadratically with number of lines in a change; now linear.
- Time complexity of adding `n` selections to a group was `O(n^2)`. Now it is `O(n log n)`, even if the selections are added one by one.
Also fix a subtle bug I found in `Group::newest_mut`: It returned a mutable reference that allowed breaking the *sorted* invariant of the selection group. The new implementation moves the element to invalidated space before returning a reference (internally to `LazyInvariantVec`), so that if it is mutated it will be moved to its correct location.
### Important Notes
New APIs:
- `NonEmptyVec::extend_at` supports inserting a sequence of elements at a location, with asymptotically-better performance than a series of `insert`s. (This is a subset of the functionality of `Vec::splice`, a function which we can't safely offer for `NonEmptyVec`).
- `LazyInvariantVec` supports lazily-restoring an invariant on a vector. For an invariant such as *sorted* (or in this case, *sorted and merged*), this allows asymptotically-better performance than maintaining the invariant with each mutation.
This PR fixes the `code_to_insert` method of entry to insert valid code according to the newest language version. Also created a separate method for getting imports required by given entry.
Now, method entries do not add imports (except when they are extensions), and are insterted with place for this type `_.method`. Static methods and constructors are inserted with the type name, and proper import for type is added.
There are some additional work done:
* The ReferentName and NormalizedName were removed, as we are now case-sensitive.
* All QualifiedName structures were replaced with new one in `name` module, as there is no longer functional difference between type qualified name and module qualified name.
* The QualifiedName structure removes "Main" module segment where it is not necessary, thus simplifying our code base and avoiding potential issues.
* Added macro `mock_suggestion_database` which should make creating consistent mocks of SuggestionDatabase much simpler.
* Fixed bug where the visualization preview show no value for some time.

# Important Notes
The tests in controller/searcher.rs file are not of the best quality, but those will be overhauled anyway when implementing my next task.
This `Slider` component allows adjusting a numeric value with the mouse. The value is increased or decreased by clicking on the component and dragging it to the left or right.
The `Slider` has a configurable default value. `Ctrl`+clicking on the component resets its value to that default. When the value is moved away from the default, the value is printed in **bold**.
The `Slider` precision is increased or decreased by clicking the component and dragging upward or downward. This precision influences how quickly the value changes when the mouse moves horizontally, the steps in which the value is incremented or decremented, and the number of digits used to display the value. There is a margin around the component within which the precision is not changed. Beyond this margin, the precision is increased or decreased in powers of 10 (e.g. `0.1` -> `0.01` -> `0.001` when moving the mouse downwards, or `0.1` -> `1.0` -> `10.0` when moving the mouse upwards). The margin and distance between consecutive steps along the vertical axis are configurable.
The value of the `Slider` is limited to a configurable range, and cannot be adjusted beyond that range. A colored bar fills the component to indicate the current value within the range.

#### Future additions
This is the first iteration of the `Slider` component. Additional features are planned for the future:
* Textual editing of the value.
* Improved visual feedback on precision changes.
* Additional out-of-range behaviors.
Libraries: Revert changes that were necessitated by a new rule we have decided not to introduce.
Parser:
- Support mixed constructors/bindings in types.
- Disallow zero-length hex sequences in character escapes: `\x`, `\u`, `\u{}`, `\U`, `\U{}` are no longer legal synonyms for `\0` (matches old parser behavior).
Ensure all tokens from the input are represented in trees resulting from invalid inputs--tests now cover every reachable code line that creates an `Invalid` node. (Also implemented stricter validation, mainly of `import`/`export` statements.)
