And video players - some of them use OpenGL to accelerate 2D. See e.g. http://www.mplayerhq.hu/DOCS/video.html#2.3.1.10 but I don't know if this is the case for 3DFX. And probably some games - I remember RTCW intro where there was a videoprojector displaying a movie onto the wall... But, I'm sure that these situations can be easily detected and avoided with carefull planning, for e.g., have a 2nd texture age that says how many times a texture as been uploaded and only make the compression once that number is reasonable (or just >1).
