When generating test data, we need to make sure the interpretation of
the data is the same regardless of endianess. That is, the pixel value
for each channel is the same on both little and big-endians.
This fixes a test failure on ppc64 (big-endian).

This places a heavier emphasis on solid images than the other fuzz testers,
and tests both single-pixel repeating bitmap images as well as those created
using pixman_image_create_solid_fill(). In the former case, it also
exercises the case where the bitmap contents are written to after the
image's first use, which is not a use-case that any other test has
previously covered.
[Pekka: added the default case to the switch in test_solid ().]
