19 * IMPORTANT:
20 *
21 * There is an old copy of this file in system/core/include/system/window.h, which exists only
22 * for backward source compatibility.
23 * But there are binaries out there as well, so this version of window.h must stay binary
24 * backward compatible with the one found in system/core.
25 *
26 *
27 * Source compatibility is also required for now, because this is how we're handling the
28 * transition from system/core/include (global include path) to nativewindow/include.
