Hmm the proposal does not imply to configure them dynamically.
It says the manipulation takes place at update (texImage2D usage),
exactly like GL's GENERATE_MIPMAP tex parameter.

Implementations of texImage2D that currently do :

if (flipY)

Would do :

if (currentlyBoundTexture && currentlyBoundTexture->flipY)

Or is there something I overlook here??
