We were clowing through all the Pango caches for no benefit.
It made the test generation stuck in fontconfig loops instead of
quickly generating tests.
So don't do that and limit the different fonts to some reasonable list
of options.
Load random strings from /usr/share/dict/words instead of reusing the
same 10 words all the time. That way, we get closer to the real world
use case of having a full alphabet.
Rename the surface getter to peek, following other render
node getters, and make the surface-based constructor private,
since it is not something we want to encourage.
Update all callers.
Replace uses of VLAs (variable-length arrays) using g_newa(), since
Visual Studio builds will unlikely ever support VLAs (which became optional
in C11).

Little tool that creates a bunch of test files to throw add the
rendernode binary.
They should really be part of a testsuite, but we have none, so OI just
put them here.
