This implements only one of the two forms of this function,
ctx.fill(winding_rule).
Also tweaks the quadratic curve demo to have a nice looking filled
shape.
Everyone who constructs an Object must now pass a prototype object when
applicable. There's still a fair amount of code that passes something
fetched from the Interpreter, but this brings us closer to being able
to detach prototypes from Interpreter eventually.
This patch adds the following methods to CanvasRenderingContext2D:
- beginPath()
- moveTo(x, y)
- lineTo(x, y)
- closePath()
- stroke()
We also add the lineWidth property. :^)
Add an implementation of CanvasRenderingContext2DWrapper.strokeRect().
While implementing this I fixed fillRect() and the new strokeRect() to
honor the .scale() and .translate() values that had previously been plumbed.
Also enhance the canvas.html demo to utilize strokeRect(), scale(), and translate().
Instead of implementing every native function as a lambda function,
use static member functions instead.
This makes it easier to navigate the code + backtraces look nicer. :^)
This patch adds HTMLCanvasElement along with a LayoutCanvas object.
The DOM and layout parts are very similar to <img> elements.
The <canvas> element holds a Gfx::Bitmap which is sized according to
the "width" and "height" attributes on the element.
Calling .getContext("2d") on a <canvas> element gives you a context
object that draws into the underlying Gfx::Bitmap of the <canvas>.
The context weakly points to the <canvas> which allows it to outlive
the canvas element if needed.
This is really quite cool. :^)
