The real blocker for implementing OpenGL (the version 3.0 in particular) is floating-point renderbuffers:

Interested about the floating point textures being enabled in Debian. I hadn't seen any discussion of it on the relevant graphics lists, but maybe I missed it. Is the reasoning here that the patent only covers the implementation of the rendering pipeline using FP textures and so hardware-backed drivers can freely use them since the patented algorithms are all in the hardware? Or are the patents just being ignored by the Debian folks? I hope people aren't just ignoring it in any way, because the FP patent is being actively used to harass and shakedown organizations: http://www.patentlyapple.com/patentl...nst-apple.html

A lot of other stuff that was disabled due to patents has recently been enabled again, H264 encoding, MP3 encoding etc.
I wouldn't be surprised if libtxc-dxtn would be accepted too, if somebody goes to the trouble of uploading it.
Not sure what the reasoning behind this move is though.
