I wanted to use SDL_inprint in multiple renderers, and that meant I
had to modify the library a little bit.
also, I just noticed that the smearing issue is back! Not as bad as
before, but MMC3 games seems to be affected when the screen scrolls
upwards...
wierd.
cross-platform support man. it's tricky.
I didn't want to include more libraries, but I really didn't want to
deal with cross-platform pathfinding, or coming up with a custom
config format.
I still had to slap together a janky solution for getting a folder's
absolute path across platforms, but it seems to get the job done...
tinyfiledialogs was a good band-aid, but it was always kind-of a
janky solution. Mind-you, this file-browser I threw together ain't
the nicest either, but at least it's within the main SDL window.
Now that the menu is in place, it's possible to switch between
games without restarting! Also, opening the file-picker pauses
ANESE, so that's good to finally have.
Thanks a bunch to cute_headers for a neat little cross-platform
directory traversal library, and also SDL_inprint for a quick-and-
dirty embedded font for use in the menu. Not having to bring-in
SDL_ttf is a huge load off my shoulders.
Oh, and i've noticed that `gui.cc` has started to get bloated, so
now I need to get around to cleaning it up weeeeee.
