These need to be implemented for all modes
IMO the lack of flipY is a bit of a problem, as it means that either texture coordinates have to be defined with their Y coordinate increasing in a "downward" direction, or that the shaders need to flip the textures.
Patches are always joyfully accepted :-)
Point taken :-)
But seriously, it is high on my list. We currently have a texture example from Google which renders upside down in WebKit because it relies on the currently unimplemented flipY flag.
