Ignore ctags file.
First pass at using SDL to render fonts instead of FreeType.
Re-enable mouse-handling.
TTF rendering via SDL now seems to basically work. Not perfect yet, but seems to be about 3X faster on Chrome.
Add experimental (and currently disabled) code for using SDL to load texture data. If I can iron out the kinks, it should be a lot faster.
Remove freetype since it now works using Emscripten's SDL.
Update to latest Emscripten incoming, including an SDL fix this branch depends on.
