Log Message:
Back out the previous day's broken R200 "fix" -- the same number of
coords are always emitted.  Fix the real problem, which was not enough
regs being initialized in ati_draw.c.  Fix a typo that was resulting in
alpha coming out as 0 * src or 0 * broken instead of src * 1 or src *
mask.  Assign the blending results to R0, as appears to be necessary.
Unbreak the dst-alpha-blend-with-no-dst-alpha code.  Yow.  And set the
right DMA count for the r200 traps code.

+	(R200PrepareComposite):
+	Revert last night's r200 render fix.  Something went wrong in my
+	testing, because that "fix" could have only made the situation worse.
+	Remember, coords are emitted even when they aren't needed.  Set
+	TX[CA]BLEND2_0 correctly, after rereading the X.org code, and remove a
+	couple of XXXs on code that appears correct.  R200 render is still
+	broken -- working on it.
