[Bug 35144] r300g should advertise GL_ARB_half_float_vertex on rv350

--- Comment #1 from Marek Olšák maraeo@gmail.com 2011-03-09 07:11:42 PST --- rv350 really can't do ARB_half_float_vertex. I tested it on RV350 long time ago and it locked up pretty hard. fglrx lies and uses some fallback probably. If you really need this extension, I can enable the fallback for r300g too.

r3xx cannot do GL_EXT_texture_swizzle with compressed textures, so it's disabled if the S3TC lib is available and enabled otherwise. fglrx here lies again and I don't think they use any kind of fallback.
