There would be no advantage for r300g.

The problem with r300g is that it cannot do depth clamping without disabling
the clipping entirely. There is only one big switch called CLIP_DISABLE, wh=
ich
"Disables clip code generation and clipping process for TCL" and =
is enough to
pass the ARB_depth_clamp piglit tests. However it has caused issues like
thousands of random/misplaced triangles on the screen. I think the lack of =
XY
clipping is the problem and the switch was probably only meant to be used w=
ith
software vertex processing.
