Don't try this at home kids. Finally had to do it like this, alternative was just getting slowly insane (I spent lot of time on futile attempts to make it in the "right" way, it doesn't even show any texture with UNPACK_FLIP_Y_WEBGL toggled on).

For some reason point sprites in "natural" orientation are upside down :S

I think normal map scale needs to be now positive, though not sure, it just looks closer to how it was before with positive scale, also mole on the right cheek is elevated instead of sunk.

Previous one had messed up mouth.

Still our normal mapped models now look different than before flipping. Not sure if this is desired or some problem (tangents do depend on UVs).

This fixes postprocessing example.

Tomorrow Geometries and CanvasRenderer.

Please note that render target must be power-of-2 sized for this trick to work. Other option would be to change directly UVs in the geometry (though that would make it harder to swap image vs render target as texture or to share geometry between objects using materials with images vs render targets).

Fixes #2164

I run chrome with the flag `--allow-file-access-from-files` instead of doing a web server so I wasn't seeing these.
