[Mesa-dev] [PATCH] gallium: fix drivers to report something for PIPE_CAP_VIEWPORT_SUBPIXEL_BITS

This is not correct.
The problem here is that there's only a viewport subpixel accuracy
query, but the state tracker uses this to both set subpixel (which is
raterization subpixel accuracy) as well as viewport subpixel bits.
The former needs to be at least 4 (dx10 requires 8), whereas the latter
still is ok to be 0.
For instance, llvmpipe and probably a bunch of other drivers would have
8 subpixel bits for rasterization, but they use actual integers for
viewport bounds, hence 0 bits. It would be incorrect to report 8 bits
for viewport accuracy (even though without msaa it matters little).
So I suspect to fix this properly you'd need a new pipe cap bit (whereas
0 as default for viewport subpixels would be just fine, but not for
rasterization subpixel).
