Andreas Kling e63f68661f LibWeb: Have ImageProvider bitmap getter take optional size argument
This allows the painting subsystem to request a bitmap with the exact
size needed for painting, instead of being limited to "just give me a
bitmap" (which was perfectly enough for raster images, but not for
vector graphics).
