Attached are patches to enable support for GL_ARB_vertex_program in the
r200 driver. I've tested it on my Radeon 9000 Pro and found no problems.
I decided against including support for GL_NV_vertex_program, since
the only programs that support the NV version but not the ARB one are
some Nvidia demos. Other programs might use an Nvidia-optimized version
if NV_vertex_program is available and use an ATI-optimized one if only
the ARB version is there. Since Nvidia-optimized means more instructions
and fewer temporary variables, while ATI-optimized means more temporary
variables and fewer instructions the ATI optimized ones should run
faster on this software-emulation of vertex programs.
