We don't really need HTMLImageElement in workers. The only places where
WebGL takes an HTMLImageElement one can pass the corresponding
ImageData. We could add some sort of convenience function for getting
said ImageData out of an HTMLImageElement, if desired, to avoid having
to roundtrip through a 2d canvas context.
Alternately, in the interests of efficiency, we could make it possible
to pass an HTMLImageElement to a worker and get an opaque thing that
represents its data (actual data plus format information) to avoid
forcing conversions to RGBA.
