f0c5f77f99 LibWeb: Remove unecessary dependence on Window from HTML classes 
These classes only needed Window to get at its realm. Pass a realm
directly to construct HTML classes.

ad04d7ac9b LibWeb: Move ExceptionOr from DOM/ to WebIDL/ 
This is a concept fully defined in the Web IDL spec and doesn't belong
in the DOM directory/namespace - not even DOMException, despite the name
:^)

4270ede7c4 LibWeb: Remove WRAPPER_HACK() macro 
We no longer access Bindings::FooWrapper anywhere for a Foo platform
object, so these can be removed :^)

6f433c8656 LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated 
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.

There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.

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.

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.

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.

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).

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).

6d50ff71de LibWeb: Encapsulate canvas drawing state in a struct 
This will allow us to easily add copies of the relevant canvas drawing
state to a stack, and likewise replace the current drawing  state with
an entry from that stack.

b32893eb54 LibWeb: Let canvas {fill,stroke}Style default to black, not transparent 
I don't know if the original author simply missed this or thought the
default color of Gfx::Color is black, but this meant that drawing on a
canvas without explicitly setting a fillStyle or strokeStyle first would
be drawn in transparent color and therefore be invisible.

In the spec this is indicated by a small comment in the IDL definition:

    attribute ... strokeStyle; // (default black)
    attribute ... fillStyle; // (default black)

I'm starting to question whether Gfx::Color actually *should* have a
default constructor.

b91c49364d AK: Rename adopt() to adopt_ref() 
This makes it more symmetrical with adopt_own() (which is used to
create a NonnullOwnPtr from the result of a naked new.)
