[Webkit-unassigned] [Bug 234920] ImageBitmap has poor performance on iOS

--- Comment #3 from Simon Taylor <simontaylor1 at ntlworld.com> ---
My hope as a mere web developer is that createImageBitmap will consume minimal time in the JS main thread, kick off any conversion necessary to effectively bake the source into an RGBA texture / IOSurface / whatever, and resolve the promise when it has finished that. The resulting ImageBitmap should then be able to be efficiently consumed anywhere - WebGL context, drawImage in a 2d context, or for direct display in a "bitmaprenderer" context.
