* IMPORTANT:
*
* There is an old copy of this file in system/core/include/system/window.h, which exists only
* for backward source compatibility.
* But there are binaries out there as well, so this version of window.h must stay binary
* backward compatible with the one found in system/core.
*
*
* Source compatibility is also required for now, because this is how we're handling the
* transition from system/core/include (global include path) to nativewindow/include.
