gallium: allow choosing which colorbuffers to clear
Required for glClearBuffer, which only clears one colorbuffer attachment. Example: If the first colorbuffer is float and the second one is int: pipe->clear(pipe, PIPE_CLEAR_COLOR0, float_clear_color, ...); pipe->clear(pipe, PIPE_CLEAR_COLOR1, int_clear_color, ...); This doesn't need any driver changes yet, because all drivers just use: if (flags & PIPE_CLEAR_COLOR) .. The drivers which support GL 3.0 will have to implement it properly though.
