The fallback font functions have been commented as deprecated for ~15
years now.
I cannot remember what the problem may or may not have been, so let's
just drop the comments.
Also, move the call to free a fallback font in imlib_free_font() to the
internals (avoiding to call deprecated functions if the font fallback
chain stuff should be deprecated for real some day).
- Always include config.h before Imlib2.h
Needed for X_DISPLAY_MISSING.
- Always include config.h and Imlib2.h first
Should make it more likely to spot stuff missing but required
in Imlib2.h, like stddef.h.
gtest.h apparently must be included before X headers though.
- Make sure we use the Imlib2.h here and not the one in /usr/include
Also ensure that the tests build when building without X.
