I fixed one issue related to textures that fixes a couple of the apps I'm testing with. Notably Foobillard now works on the Radeon HD 5450. Also Most of Quake 3 now works on the Radeon HD 5450, with the exception that the mirror and the portal on the introduction level don't work right due to missing support for user clip planes. The recently released Morphiller demo now also runs on the Radeon HD 5450, except the final report screen that seems to misrender a bit.
