* Re-hide SDL2 details.David Thompson2018-12-136-22/+17
| | | | | | | | | | | | | | | | | | | | | I know I'm backpedaling here, but I think it was a mistake to expose SDL2 as much as I have here. I think it's better for people just getting started to not have to wonder what SDL means. Making things as usable as possible for beginners is an important goal, and abstracting SDL2 + OpenGL things from the core game loop implementation shouldn't require sacrificing that goal. * chickadee.scm: Switch code with... * chickadee/game-loop.scm: ...this! Which is copied straight from... * chickadee/sdl.scm: ...this! Which is now deleted. * Makefile.am (SOURCES): Add game-loop.scm, remove sdl.scm. * examples/grid.scm: Update due to API breakage. * examples/lines.scm: Ditto. * examples/nine-patch.scm: Ditto. * examples/sprite.scm: Ditto. * examples/text.scm: Ditto. * examples/tiled.scm: Ditto. * doc/api.texi (Kernel): Update.

* Make the game loop modular!David Thompson2018-08-235-28/+13
| | | | | | | | | | | | | | | This is really cool! Now users can plug in whatever backend they'd like and are not forced to use SDL and OpenGL.
