implement ARB_point_parameters and ARB_point_sprite on r200. The code is nearly the same as outlined in bug #4707, except it disables perspective correction for point sprites to make them actually work. And, separate the state atom into two as the tcl parameters would overwrite vertex program parameters when active. Also implement the GL_VERTEX_PROGRAM_POINT_SIZE_ARB option to make vertex programs outputting a point size work correctly (untested). Smooth points will still always be size 1. While here, enable gouraud shading for fog when using fog coord.
