a43d892c4e LibGfx: Use the first/last color for positions before/after a gradient 
This fixes a few rendering bugs especially where the first or last
color stop had a zero alpha value. Note we can't just set the first
and last values on the gradient line to the first/last colors since
that might not be correct (e.g. have a transition hint).

6255ca4a42 LibJS: Add DisposableStack{, Prototype, Constructor} 
Since the async parts of the spec are not stage 3 at this point we don't
add AsyncDisposableStack.

bff038411a LibJS: Add using declaration support in for and for of loops 
The using declarations have kind of special behavior in for loops so
this is seperated.

541637e15a LibJS: Add using declaration support, RAII like operation in js 
In this patch only top level and not the more complicated for loop using
statements are supported. Also, as noted in the latest meeting of tc39
async parts of the spec are not stage 3 thus not included.

a746739cb0 LibJS: Add an initialize binding hint to all initialize_binding methods 
This will allow us to specify things like SyncDispose and perhaps
AsyncDispose in the future.

0d8bab82f0 LibJS: Add custom details to toBe{True, False} shown on failure 
Any test with multiple expect(...).toBe{True, False} checks is very hard
to debug.

fa030d7b9c LibJS: Clarify more errors in test-common 
Without a message these just show 'ExpectationError' even if the check
has multiple steps.

Sam Atkins
c7a66882f4 AK: Make NonnullPtrVectors shuffleable 
AK::shuffle() doesn't work on these, because their operator[] returns a
reference to the pointed-at value, instead of to the NonnullPtr itself.

ccabc8e930 LibCards+Games: Return ErrorOr from CardStack::add_all_grabbed_cards() 
...and CardGame::pick_up_cards_from_stack() which is its only caller.

c7c4d70f6e LibCards+Games: Return ErrorOr from deck-creation factory functions :^) 
Also, be smarter about appending cards to the deck: we can
unchecked_append them to the deck, since we already ensured enough
capacity earlier.

8b3a94ffbc LibCards+Games+GamesSettings: Return ErrorOr from CardStack::push() 
Very few of these calls can propagate their errors yet, but one step at
a time. :^)

83687f85df LibCards+Solitaire: Rename CardStack::move_to_stack() -> take_all() 
`a.move_to_stack(b)` sounded too much like it moves a's cards to b, when
it actually moves b's cards to a.

3423b54eb9 LibTextCodec: Make utf-16be and utf-16le codecs actually work 
There were two problems:

1. They didn't handle surrogates
2. They used signed chars, leading to eg 0x00e4 being treated as 0xffe4

Also add a basic test that catches both issues.
There's some code duplication with Utf16CodePointIterator::operator*(),
but let's get things working first.

ef275e25b8 AK: Reduce String's allocated data by one byte 
This was copied from allocation_size_for_stringimpl, which had to ensure
the string is null-terminated. String makes no such guarantee.

27a3e11f02 LibWeb: Implement the canvas gradients 
This gets:

- CanvasRenderingContext2D.createLinearGradient()
- CanvasRenderingContext2D.createConicGradient()
- CanvasRenderingContext2D.createRadialGradient()

Actually working as fill styles for paths and rectangles :^)
Getting them working for strokes is left as an exercise is
left as an exercise for the reader.

24cb57ac88 LibWeb: Update CRC2D .fillStyle and .strokeStyle to accept gradients 
While doing add some structures to hold these new fill styles and
plumb them over to the painter.

1a89d77688 LibGfx: Implement paint styles required for HTML canvas gradients 
This implements the gradients for:

- CanvasRenderingContext2D.createLinearGradient()
- CanvasRenderingContext2D.createConicGradient()
- CanvasRenderingContext2D.createRadialGradient()

As loosely defined in: https://html.spec.whatwg.org/multipage/canvas.html#fill-and-stroke-styles
(It's really not very well defined for radial gradients)

Actual implementation (for radial gradients) was done with a lot
of trial and error, then visually comparing to other browsers.

f3c0987afe LibGfx: Add Painter::fill_rect(rect, paint_style)

223cedc896 LibGfx: Update fill_path() to support taking a PaintStyle 
This means fill_path() now paints the scanlines its self rather than
calling draw_line() which easily allows each pixel along the scanline
to have a different color.

b31d768e95 LibGfx: Add paint styles and allow gradients to be used as them 
Also while here add option to disable pre-multiplied alpha for gradients
(this will be handy later).
