WebGL Video upload to SRGB8 textures is slow
The GPU codepath uses OpenGL to render the texture.
SRGB8 is not color-renderable in OpenGL. This should not be a real HW limitation.
ANGLE has more fast paths with glCopyTextureCHROMIUM, but
a) likely it doesn't do source color space conversions(?)
b) it doesn't have x flip
c) it's unclear if it does the SRGB8_ALPHA8 the same way as the current
