Does not appear to be a duplicate of 23657. Tried editing line 2088 in
r700_assembler.c and found the value to always be 0 in the test case, tried
setting to 1 and it made a real mess. Attaching image with saturate=1.0

Looked at r700SetBlendState found that ctx->Color.BlendEnabled alternated
between 0 and 1. Tried setting always to 1 did not change anything. Found the
BlendEquationRGB and BlendEquationA were GL_FUNC_ADD.

line 516 of r700_state.c didn't seem to identify my rv635 as an r600, unless
the CHIP_FAMILY_R600 is specific to R600 based devices only.

context->radeon.radeonScreen->chip_family == CHIP_FAMILY_R600, but I forced
that if block to run and it didn't make any change.

Also looked at r700BlendColor and found that the color always appeared to be
black, however altering these values didn't seem to affect anything. I am
curious as to the call to SetBlendColor at line 1723 in r700_state.c as to what
the values below it do.
