# A note on some of the USE flags:
# devil - compiles image loading stuff, recommended unless you have your own image loading code
# double-precision - uses double precision floats, runs slower.
# -
# gtk - compiles the gtk opengl renderer and platform manager
# sdl - compiles the sdl opengl renderer and platform manager
# The above two are mutually exclusive. If they are omitted, the GLX renderer and platform manager is used
# -
# gtk-config - this is separate from the renderers/platforms, it's the toolkit used for config dialogs.
# 	Uses cli if not specified.
#	 Perhaps should be renamed to avoid confusion?
# threads - Enables threading support, this is highly experimental.
