// Define this to make all operations case insensitive.
// Windows systems generally don't care much, but for Linux and Mac this can be used
// to get the same behavior as on windows.
// Additionally, this achieves full case insensitivity within the library,
// if the the same files are accessed multiple times by the program, but with not-uniform case.
// (no sane programmer should do this, anyway).
// However, on non-windows systems this will decrease performance when checking for files
// on disk (see VFSLoader.cpp).
