/*
* egltypes.h - EGL API compatibility
*
* The intention here is to support multiple EGL implementations for the
* various backends - GLX, AGL, WGL, Solo - so we define the EGL types as
* opaque handles. We also define the Native types as opaque handles for
* now, which should be fine for GLX and Solo but the others who knows.
* They can extend this later.
*
* We require that 'int' be 32 bits. Other than that this should be pretty
* portable.
*
* Derived from the OpenGL|ES 1.1 egl.h on the Khronos website:
* http://www.khronos.org/opengles/spec_headers/opengles1_1/egl.h
*
