Unfortunately the format string for a size_t, `%zu`, is not portable
to all Windows compilers, and the appropriate format string for the
fundamental type that implements size_t varies between platforms
(typically `%u` on 32-bit platforms, `%lu` on 64-bit Linux or
`%llu` on 64-bit Windows).
In gtk-demo, cast the number of search results to long, to avoid
breaking up a translatable string.
Elsewhere, use GLib's abstraction for this.

Add some more texture conversion roundtrips. They are currently
ifdefed out, since they need cicp api.
Also add another test binary for internal tests.
This is mostly an empty shell for now. We only have static instances
for srgb and srgb-linear, which we will use as markers during our
node processing.
In the future, this object may grow more instances, as well as the
ability to create them from and save them to icc profiles or cicp
data. And a color conversion API.
