| | | | | | | | | | | | | | | coordinate generation. Original code by Roland Schiedegger, with changes by myself. While here, ensure that the swtcl path does tnl_install_attrs enough when fog/specular are being (en/dis)abled. Notable effects: - projtex test works with TCL and is closer with swtcl (Bugzilla #1461) - 8/9 squares work in texgenmix instead of 3. - texcyl "reflect" mode works (GL_SPHERE_MAP is now a fallback -- unclear if the hardware can actually support it). - flickering in doom3 replaced by just plain darkness. - blocktube fixed (Bugzilla #984) - fixes stex3d

| | | | | | | the current cases for turning it on were insufficient (Bugzilla #1519, 729, 814) and it has no significant performance impact. Performance tested with quake3 in GL_LINEAR mode both with and without anisotropy, with the workaround always on or always off.

* Add Roland Scheidegger's S3TC patch. This patch does not implement theEric Anholt2004-10-071-2/+29
| | | | | | | | | | | | | | | | | (patented) S3TC/DXTC algorithms, but adds an option to dlopen a library module providing functions to do so. Because it uses dlopen, it is only enabled if USE_EXTERNAL_DXTN_LIB=1 is defined (which is only in linux-dri config, so far). It adds support for S3TC to several DRI drivers, and adds a DRI config option to force enabling S3TC even if the software compression/decompression is unavailable. This may allow people to use apps that require S3TC even though they don't have a license to implement the patented material themselves, if those apps use precompressed textures. Ideally we would get permission from the current holder of the patents to implement the algorithm in Mesa, at which point the dlopen mess could go away. Until then, this allows some to run applications they couldn't otherwise, and hopefully will provide us with more push to get the final step of getting that permission done.
