Poppler renders the PDF output of this test correctly with cairo 1.10.2 but fails with current git.
Commenting out the cairo_translate makes the PDF output render correctly with current git.
Debate rages as to the correct way to handle this. In some ways the
current output is expected due to the numerical instability in handling
the inner-focus-on-the-outer-circle. However, the result looks less than
desirable so some solution (which may not be inside cairo per-se) is
sought.
Uli Schlachter spotted that I had create reference images with sharp
edges for his tighten-bounds test case, exactly as if I had ignored
unaligned clip boxes...
Turns out I had removed the code to handle them...
The test-traps provides a reference implementation of the
traps-compositor as used by xlib, so we can use it to generate the
reference images as well. (Of course checking that test-traps is itself
correct and only differs in the renderer! ;-)

With over two thousand references images now, it is starting to make the
test directory look cluttered!
