No argument there.  I figured that there was no real chance of my patch getting
committed long-term, just figured that it partially mitigates the worst of the
problem for now.  If we can extend glamor to handle shader-based lines or
improve the software fallbacks, great...  it's just beyond what I feel
comfortable with at the moment (my background is more OpenCL, not GL, and I
just took my first real look at the glamor code this morning).
