Each of the waffle_${obj}_get_native() functions returns a correspondingly named
union waffle_native_${obj}*.
For example, waffle_window_get_native() returns union waffle_native_window*
For each platform, the header <waffle_${platform}.h> defines the native container structs. For
example, <waffle_glx.h> defines the structs waffle_glx_${obj}.
Observerve that native container structs are not defined for all platforms that waffle supports. In
particular, waffle supports Android (WAFFLE_PLATFORM_ANDROID) and MacOS via CGL
(WAFFLE_PLATFORM_CGL), but no container structs are defined for those platforms.
Presently, waffle does not expose the native objects for those platforms due to implementation difficulties.
