Hi,

I've just found some time to test the 'hw_gl_select' mesa branch.

Test case: r300g, Blender 2.49b (default scene : cube + lamp + camera)

This does not seem to work very well:
 - I'm having some troubles to select objects (mainly the lamp)
 - selection behavior changes between fullscreen/window mode (the camera is
almost impossible to select in FS)
(when selection fails zData[0]==1.0 and zData[1]==0.0)

I've tested with this program too:
http://sydney.edu.au/engineering/it/~tapted/slow_glselect.html
It doesn't work when MESA_HW_SELECT is set, but works properly without.

This is not the same PC I've tested the earlier patches on, so maybe I've got
something wrong on this one.

Lars did you already test this branch on r600g ?
