To use:
- Rename source/PROJECT_NAME
- Replace #include "PROJECT_NAME/..." statements in source files


Invocations for recording and video output:
./PROJECT_NAME --record inputsession
./PROJECT_NAME --playback inputsession --video-out videofiles --headless
ffmpeg -framerate 60 -pattern_type glob -i "videofiles/frame*.png" -i videofiles/audio.wav -f mp4 -vf scale=512x384,format=yuv420p -sws_flags neighbor video.mp4


TODO:
- Adopt SpriteDrawBuffer from Leaf's Odyssey
- Pause menu with preferences (adopt from Leaf's Odyssey, and fix GameSession sound/music volume API)
- There's no music output during recording; why? Threaded loader never completes? (should force synchronous load)
- Room traversal:
 - Handle exiting to nonexistent room (maybe not for template)
 - Traversal across zone layers (maybe not for template)
- Something for interact button to do? (could be climb up/down ladder; see zone layer traversal)
- Improve auto-tiling behavior (maybe not for template)
 - Inner corners are bad
 - Include adjacent room tiles at edge, somehow
- Undo across rooms?
