- * Test program, which can detect some problems with affine transformations
- * in pixman. Testing is done by running lots of random SRC and OVER
- * compositing operations a8r8g8b8, x8a8r8g8b8, r5g6b5 and a8 color formats
- * with random scaled, rotated and translated transforms.
- *
- * Script 'fuzzer-find-diff.pl' can be used to narrow down the problem in
- * the case of test failure.
