Just the call on getImageData to extract texture and read all pixels from an image can take 15s if CORS is in the play...

you don't call getImageData to extract a texture data. You load the image, make a texture of it, and then apply all postprocessing effects with a WebGL shader.

OK, thanks for the hint! I'll try to play with CORSed image texture binding to see what the performance is.
