 | 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. |
