Hi Roland, I see you've been here before!

I no longer have the Ubuntu Maverick install I was testing with earlier (I
don't have the disk it was on anymore), but I do have here an Ubuntu Lucid
install (same hardware) with Mesa 7.7.1, which gives me this:

$ glxinfo -l | grep -i point
    GL_ARB_occlusion_query, GL_ARB_point_parameters, GL_ARB_point_sprite, 
    GL_EXT_packed_pixels, GL_EXT_point_parameters, GL_EXT_polygon_offset, 

That seems to agree with what you said.

Your patch applies cleanly to 7.7.1, and indeed, it makes the points big! The
modified "point" demo, "pointblast" (only w/"Point smooth off"), and Wings3D
all now do as they should. Should I test your patch with bleeding-edge code?

I don't know what to make of the patch tweaking generic code instead of driver
code, but it surely solves the problem for me. Could this, or some form of
this, be committed into the tree?
