Gallium supported only a single viewport/scissor combination. This

Would it be better if this were PIPE_CAP_MAX_VIEWPORTS instead? Though I
guess there's no real need right now to support anything but 16 (as
that's needed by d3d10/11, and is the minimum supported value for GL,
though GL would allow for more), so I don't have a strong opinion on that.
I second this suggestion.
