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.
