Subject: [PATCH] [test] Add group-paint

The experience of running the entire test suite under cairo_push_group()
did at least reveal that there was a potential bug in the pdf backend.
This test is just the simplest of drawing operations - simply filling
the similar surface with solid blue, and then blitting that surface to
the destination.
