Message:

Translate window rendering in console/SSR with translation GC

In full-screen mode (such as text/console) and server-side rendering
we need other mechanism than memory GC to translate the coordinates
while rendering. We use a translation GC (xlategc).

Note the extensively elaborate testing of this very simple GC seems
quite overboard. At least the very elaborate test_gc_t could be hoisted
into a library and used wherever a test GC is required.
