Added a note about OpenGL support on Linux (again) to controlcandidates.md now that I noticed it while looking for a way to test GTK+/Wayland...
Added code to the GTK+ Area to print the GdkKeymapKeys for a given key value. For GTK+/X11 it appears that we can just use the keyval field... that just leaves GTK+/Wayland (see previous commit). If the same applies, we'll need to see if I can feed artificial keycodes in and it'll still work as expected...
Finished writing what I need for the GTK+ key equivalency test: display of GDK_KEYMAP_A and GDK_KEYMAP_a to see if I can do what I want to do (map back).
Finally finished getting ready for Area keyboard input; now just need to figure out which keys to support. Also a Wayland-related TODO.
