/* Platform-specific types and definitions for egl.h

 *

 * Adopters may modify khrplatform.h and this file to suit their platform.

 * You are encouraged to submit all modifications to the Khronos group so that

 * they can be included in future versions of this file.  Please submit changes

 * by sending them to the public Khronos Bugzilla (http://khronos.org/bugzilla)

 * by filing a bug against product "EGL" component "Registry".

 * EGL functions should be prototyped as:

 *

 * EGLAPI return-type EGLAPIENTRY eglFunction(arguments);

 * typedef return-type (EXPAPIENTRYP PFNEGLFUNCTIONPROC) (arguments);

 *

 * KHRONOS_APICALL and KHRONOS_APIENTRY are defined in KHR/khrplatform.h

/* The types NativeDisplayType, NativeWindowType, and NativePixmapType

 * are aliases of window-system-dependent types, such as X Display * or

 * Windows Device Context. They must be defined in platform-specific

 * code below. The EGL-prefixed versions of Native*Type are the same

 * types, renamed in EGL 1.3 so all types in the API start with "EGL".

 *

 * Khronos STRONGLY RECOMMENDS that you use the default definitions

 * provided below, since these changes affect both binary and source

 * portability of applications using EGL running on different EGL

 * implementations.
