Instead of painting DecodedImageData by first asking it for a bitmap
and then painting that, this commit adds two new APIs:
- frame_rect(frame_index):
Gets the size of the animation frame at the given index.
- paint(context, ...):
Paints the DecodedImageData into a DisplayListRecordingContext.
The main powerful thing here is that this allows SVGDecodedImageData
to render itself using the GPU when available.
