Move the struct image_header and get_image_prop() into a header where we
can share these useful helpers between more test code. While doing that,
drop the unused field 'depth', rename into image_header_from(), and
introduce a helper to get u32 pointer to the beginning of a row. These
helpers should make pixel iterating code easier to read and safer (less
room for mistakes in address computations, and asserts).
Use the shared 'struct image_header' instead of the local one. The
intention is to make the code easier to read by using the same helpers
everywhere.
Width, height and stride use type 'int' because Pixman API uses that
too.

Move gen_ramp_rgb() down in the file where the TEST() specific code
begins. This way we first have a big block of fixture setup code which
creates an ICC profile, and the next big block is the actual test client
code. gen_ramp_rgb() belongs with the latter.
This makes the file structure slightly more logical.
This is a pure code move, no changes at all.

This name describes better what this test does. In the future another
TEST() for alpha blending will be added. Both of them will be using
matrix-shaper and cLUT output profiles.

The new name better matches the contents of the test.
Currently the test creates output ICC profiles with matrix-shaper and
cLUT forms, and tests that basic color conversion from input to output
color space is correct.
The common theme in this test program is to create ICC profiles to be
used as output profiles. In the future this can include more kinds of
testing, e.g. linear blending. OTOH, this test program will always be
limited to SDR because HDR testing probably will not use ICC files.
