Ahhh legacy functionality from hell...

I'm wondering if it would be possible to omit the rasterPos execution
completely, by incorporating it into drawPixels etc. at least in the
hopefully common case there's no state changes affecting the results i
The st_RasterPos() function goes to great pains to implement the
rasterpos transformation. It basically uses gallium's draw module to
execute the vertex shader to draw a point, then capture that point's
attributes.
But glRasterPos isn't typically used with a vertex shader so we can
usually use th
