gallium: new draw stage for polygon stipple.
For hardware without native polygon stipple. Create a 32x32 alpha texture
that encodes the stipple pattern. Modify the user's fragment program to
sample the texture (with gl_FragCoord) and kill the fragment according to
the texel value.
Temporarily enabled in softpipe driver, replacing the sp_quad_stipple.c step.
