(iOS) Skeleton camera driver
(iOS) Start adding camera code - right now fails at camera_init
(iOS) Camera - add two links for reference
(iOS) Flesh out camera driver some more - still no image - have to
generate texture cache in RAGameView.m
(iOS) Camera  - implement most of the code inside RAGameView -
totally untested - C camera driver is now a shim and will just
need to dial into the RAGameView camera driver parts
(iOS) Integrate iOS camera driver into RAGameView.m - CVOpenGLESTextureCacheCreateTextureFromImage keeps failing right now so instancingviewer camera core doesn't yet work
(iOS) Camera works now with instancingviewer camera core - it's glitchy
though - still seems to render to default framebuffer too - which we
need to avoid
(iOS) Camera - do glBindTexture(GL_TEXTURE_2D, 0) at end of processFrame
to prevent stale garbage texture frame from being output to main
framebuffer. There is still flickering going on though
add sample overlay using per-button images
(iOS) Change way setting menu items are created
(Apple) Start to refactor setting data structure; clean up iOS code some
(iOS) Improve handling of path settings some:
   The file browser will start in the directory of the currently seleected file.
   The setting menu will display only the filename instead of the full path.
   Path settings can specify a list of extensions to search for.
(iOS) Don't crash when creating a file browser with a null extension list
video_omap: complete rework and refactoring of the driver
video_omap: add to build system
video_omap: remove debug message
(iOS) Move iOS settings code into iOS specific file and fix the issue where every compile unit would get its own copy of apple_frontend_settings
(iOS) Add an enumeration type setting and use it for selecting screen orientations and bluetooth mode
Clean up float FBO handling a bit.

Fallback to UNORM if not supported.
