This ensures we use EGLNativeWindowType and EGLNativeDisplayType everywhere instead. The previous names come from EGL 1.2 but it seems reasonable to require more recent EGL versions. If someone wanted to add compatibility for EGL 1.2 later it would be straightforward to define the new names to the old. Reviewed-by: Neil Roberts <neil@linux.intel.com>
