Connect the gui to the new shaping logic; this means that we
can now correctly render fg/bg color when the cursor moves
through the cells that comprise a ligature.

This function is intended to deal with certain kinds of ligatures
and certain combining sequences that don't have corresponding glyphs.
It isn't hooked up to the gui yet, but does have unit tests that
are probably mostly correct.

https://learnopengl.com/Advanced-Lighting/Gamma-Correction suggests
some good practices:
* Only enable SRGB output on the final draw call, so that all prior
stages can operate on linear values and avoid converting to/from
linear multiple times.
* The SRGBA textures automatically linearize when sampled, but:
* The RGB data must be SRGB (non-linear)
* The A channel is assumed to be linear!
This commit nudges us closer to that by:
* Converting the freetype coverage map from its linear value to
non-linear when rasterizing.
* Splitting the shader files into one per stage (background, lines,
glyphs) and only setting outputs_srgb for the glyph stage

A couple of times today while debugging things on wayland, I lost
keyboard input to wezterm.
I don't know if that is strictly a wezterm bug, or just a general
wayland bug (not long after, the whole mutter session hung, and
somehow wedged all processes with my uid).
So, this is a quick stab in that direction.
This fixes a longstanding issue under mutter where client side
decorations are in use. The decorations were being drawn too
early in the initialization of the window which could leave them
off-screen and weird. This was masked by a couple of mutter
related bugs with client side decorations.
With these changes I now get sane decorations under mutter,
and the toggle fullscreen action is now enabled as well!

However, I'm not able to create wayland windows any more on my nvidia
system (either with or without this change).
I don't know if this is specific to my nvidia drivers or something else

Dead key processing respects the
`send_composed_key_when_left_alt_is_pressed` and
`send_composed_key_when_right_alt_is_pressed` options.

* Adds `CopyTo` and `PasteFrom` assignments that specify the
destination/source.
* Adds `default_clipboard_copy_destination` and `default_paste_source`
config options that specify the default destination/source for
existing `Copy` and `Paste` operations (for @bew)
* Deprecating `PastePrimarySelection` in favor of `PasteFrom`.
* Added `CTRL-Insert` -> `Copy` (for @Babar)
Aside from the new key assignment, these changes shouldn't change
the default behavior, but do make it easier to consider changing
that in a later commit.
They should allow for example:
* Set `default_clipboard_copy_destination = "PrimarySelection"` to
prevent populating the clipboard by default when using the mouse.
* Overriding the CTRL-Insert, CTRL-SHIFT-C to explicitly populate
the clipboard
* Set `default_paste_source = "PrimarySelection"` for middle click
to paste the selection.
* Overriding SHIFT-Insert, CTRL-SHIFT-V to explicitly paste from
the clipboard.

The heart of this issue was that the resize callbacks have two
layers of state; one in the low level window and one in the application
level window.
On Windows, the system triggers the low level callback prior to
opengl being initialized. Since the application level depends on
the opengl state, there are some code paths where it NOPs and
returns early if opengl isn't yet initialized.
When the system-wide display scaling is set to say 200%, the application
layer can't know the effective DPI of the window it is creating because
it doesn't know which monitor will be used or what its DPI will be.
New windows are created at the default DPI of 96, and we rely on the
resize events to detect the actual DPI and adjust the scaling in
the window.
The early call of the resize callback meant that the low level and
application level size/dpi state was out of sync and the result was
that the window had half as many pixels as it should, but that the
terminal model was still sized as though it had the correct amount
(twice as many as visible). This resulted in the window being too
small for the viewport.
The resolution is simple: we now suppress emitting the resize processing
until opengl has been initialized.
The test scenario for this is:
* Set system scaling to 100%
* Launch wezterm
* Set system scaling to 200%
* Observe that wezterm scales to match
* Press CTRL-SHIFT-N to spawn a new window
* Observe that the new window size matches the other window (previously
this one would be half the size)
While I was looking at this, I noticed that the manifest didn't
match the DPI awareness that we have in the code, so update that.

This adopts a similar technique to that used to pass the wezterm
config to the term crate, but this time it is for passing it to
the window crate.
The use_ime option has been ported over to this new mechanism.
Hooks up toggling fullscreen mode on macos, with plumbing for
other systems.
I prefer not to use the "modern fullscreen" mode because I find
the transition animations in macOS are horrendously slow.
I'll make an option to allow selecting whether that is used or not
in a follow-on diff.

When we decode a key event from X11 into a `KeyCode::Char(_)` variant,
that result has already factored in the result of the SHIFT modifier
state.
That makes SHIFT largely useless for unicode keys; we do want to
preserve the SHIFT modifier for keys such as the arrow keys.
This commit removes SHIFT from the `KeyEvent::modifiers` for
`KeyCode::Char(_)` variants so that those modifiers don't get
in the way of keymap lookups.

I didn't recreate precisely the situation in the issue, but I
tried pressing both `AltGr 8` and `CTRL ALT 8` with a DEU
layout active and both now result in `[` being emitted.
