 /* fglrx uses fixed inputs as follows for conventional attribs.

+   generic attribs use non-fixed assignment, fglrx will always use the
+   lowest attrib values available. We'll just do the same.
+   There are 12 generic attribs possible, corresponding to attrib 0, 2-11
+   and 13 in a hw vertex prog.
+   attr 1 and 12 aren't used for generic attribs as those cannot be made vec4
+   (correspond to vertex normal/weight - maybe weight actually could be made vec4).
+   Additionally, not more than 12 arrays in total are possible I think.
    attr 0 is pos, R200_VTX_XY1|R200_VTX_Z1|R200_VTX_W1 in R200_SE_VTX_FMT_0
    attr 2-5 use colors 0-3 (R200_VTX_FP_RGBA << R200_VTX_COLOR_0/1/2/3_SHIFT in R200_SE_VTX_FMT_0)
    attr 6-11 use tex 0-5 (4 << R200_VTX_TEX0/1/2/3/4/5_COMP_CNT_SHIFT in R200_SE_VTX_FMT_1)
    attr 13 uses vtx1 pos (R200_VTX_XY1|R200_VTX_Z1|R200_VTX_W1 in R200_SE_VTX_FMT_0)
-   generic attribs would require some more work (dma regions, renaming). */
