/**
* Public EGL API entrypoints
*
* Generally, we use the EGLDisplay parameter as a key to lookup the
* appropriate device driver handle, then jump though the driver's
* dispatch table to handle the function.
*
* That allows us the option of supporting multiple, simultaneous,
* heterogeneous hardware devices in the future.
*
* The EGLDisplay, EGLConfig, EGLContext and EGLSurface types are
* opaque handles implemented with 32-bit unsigned integers.
* It's up to the driver function or fallback function to look up the
* handle and get an object.
* By using opaque handles, we leave open the possibility of having
* indirect rendering in the future, like GLX.
*
*
* Notes on naming conventions:
*
* eglFooBar - public EGL function
* EGL_FOO_BAR - public EGL token
* EGLDatatype - public EGL datatype
*
* _eglFooBar - private EGL function
* _EGLDatatype - private EGL datatype, typedef'd struct
* _egl_struct - private EGL struct, non-typedef'd
*
