62b561e2e1 LibWeb: Extract CanvasDrawPath class from CRC2D 
Again, this is an entirely virtual class since the methods involve
direct access to the Painter. Though, maybe I could just expose the
Painter...

c0494988ed LibWeb: Extract CanvasRect class from CRC2D 
This one requires drawing to the canvas, so it doesn't make so much
sense to move the implementation over.

aa87b9699e LibWeb: Extract CanvasTransform class from CRC2D 
The implementation of this got a little funky, because it has to access
methods from CanvasState.

As with CanvasPath, this is to better match the spec IDL.

a37ab7b9f8 LibWeb: Extract CanvasPath class from CRC2D 
This better matches the spec, and makes it possible for things like
Path2D to reuse the same implementation without duplicate code. :^)

adf8341c4e LibWeb: Forward CRC2D's ref count to HTMLCanvasElement 
This allows HTMLCanvasElement and CRC2D to share their lifetime, as JS
allows them to arbitrarily access them at any time and CRC2D.canvas
expects a non-null return value.

works without this.

e890cd5464 LibWeb: Implement CanvasRenderingContext2D.getImageData() 
The actual copying of the pixel values into the created ImageData object
is a bit ugly, but Gfx::Painter doesn't like the underlying RGBA8888
bitmap.

08608932cc LibWeb: Change CanvasRenderingContext2D.createImageData() args to long 
Not sure why these are doubles in the IDL definition, both the IDL in
the spec and the implementation in the CanvasRenderingContext2D class
use integers.

3f3326f1dc LibWeb: Implement CanvasRenderingContext2D.drawImage() closer to spec 
Also add support for HTMLCanvasElement for the image parameter, leading
to replacing HTMLImageElement with the CanvasImageSource Variant type.

Also stub out the 'check the usability of the image argument' and 'is
not origin-clean' operations, while taking into consideration that these
can throw (and require DOM::ExceptionOr).

926d5271b4 LibWeb: Forward CanvasRenderingContext.strokeText() to fillText() 
This is a hack until we get an actual text stroking implementation.

dc3bf32307 LibWeb: Add barebones CanvasGradient object 
Also add the CanvasRenderingContext2D APIs to go along with it.
Note that it can't be used for anything yet.

9121cc7cae LibWeb: Implement CanvasRenderingContext2D.measureText 
This requires an implementation of the "text preparation algorithm" as
specified here:

html.spec.whatwg.org/multipage/canvas.html#text-preparation-algorithm

However, we're missing a lot of things such as the
CanvasTextDrawingStyles interface, so most of the algorithm was not
implemented. Additionally, we also are not able to use a LineBox like
the algorithm suggests, because our layouting infra is not up to the
task yet. The prepare_text function does nothing other than figuring out
the width of the given text and return glyphs with offsets at the
moment.

1298c27ca9 LibWeb: Implement CanvasRenderingContext2D.isContextLost() 
Note that we don't implement the "context lost steps" yet, so this will
always return the initial value (false).

00114ab01d LibWeb: Add a naive implemention of CanvasRenderingContext2D::fill_text 
This doesnt actually account for several unimplemented attributes
(like ltr/rtl, alignment, etc) yet, so this should be expanded in
the future.

  undefined fill(optional CanvasFillRule fillRule = "nonzero");
