**
** EGL types and resources are to be typedef'ed with appropriate platform
** dependent resource handle types. EGLint must be an integer of at least
** 32-bit.
**
** NativeDisplayType, NativeWindowType and NativePixmapType are to be
** replaced with corresponding types of the native window system in egl.h.
**
** EGL and native handle values must match their types.
