Before this change we were serializing them in a bogus 8-digit hex color
format that isn't actually recognized by HTML.
This code will need more work when we start supporting color spaces
other than sRGB.
This thing is essentially a wrapper around an SkPath, although we do
some indirection via a PathImpl class to keep the door open for
alternative rasterizer/path backends in the future.
We also update the 2D canvas code, since that was the only code that
used Painter+DeprecatedPath, and this allows us to just drop that
code instead of temporarily supporting it until the next commit.
Implement setLineDash() and getLineDash() in CanvasPathDrawingStyles,
which write/read from the CanvasState object.
This doesn't implement the actual drawing of a dashed line, but at least
sites using the Chart.js library no longer fail with an exception.
Unfortunately the Painter classes don't support dashed/dotted lines
based on segments yet.
A bunch of this is leftover from pre porting over to new AK::String.
For example, for functions which previously took a ByteString const&
now accepting a StringView.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

Add the CanvasTextDrawingStyles mixin with the textAlign and
textBaseline attributes. Update fill_text in CanvasRenderingContext2D
to move the text rect by the text align and text baseline attributes.
Wrote a simple HTML example to showcase the new features.
Works for fills and strokes (using colors, gradients, or patterns),
along with images.
fill_rect() has been updated to use fill_path(), which allows it to
easily transform the rect, and already supports opacity.

This allows clipping your drawing by any path you like! To do this
all painting has been wrapped around a new draw_clipped() helper
method, which handles the clipping before/after painting.
Note: This clipping is currently missing support for intersecting
clip paths.
We now select between nearest neighbor and bilinear filtering when
scaling images in CRC2D.drawImage().
This patch also adds CRC2D.imageSmoothingQuality but it's ignored for
now as we don't have a bunch of different quality levels to map it to.
Work towards #17993 (Ruffle Flash Player)
This is a first pass at implementing CRC2D.createPattern() and the
associated CanvasPattern object. This implementation only works for a
few of the required image sources [like CRC2D.drawImage()], and does
not yet support transforms. Other than that it supports everything
else (which is mainly the various repeat modes).
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.
