** egltypes.h is platform dependent. It defines:

**     - EGL types and resources

**     - Native types

**     - EGL and native handle values

**

** 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.
