Subject: [PATCH] Add new paint-repeat test

I added this test originally to make it easier to debug
some recent bugs, (the test suite did have some repeating
in the checkered backgrounds, but with an offset of 0,
and then also in trap clip with an offset larger than the
surface itself). This test exercises repeating more directly.

It also triggers a bug in the PostScript backend that I've
not yet investigated. So the test does fail currently.
