/*
- * 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
