Ryan C. Gordon 99c9727dc0 timer: Added SDL_GetTicks64(), for a timer that doesn't wrap every ~49 days. ... Note that this removes the timeGetTime() fallback on Windows; it is a 32-bit counter and SDL2 should never choose to use it, as it only is needed if QueryPerformanceCounter() isn't available, and QPC is _always_ available on Windows XP and later. OS/2 has a similar situation, but since it isn't clear to me that similar promises can be made about DosTmrQueryTime() even in modern times, I decided to leave the fallback in, with some heroic measures added to try to provide a true 64-bit tick counter despite the 49-day wraparound. That approach can migrate to Windows too, if we discover some truly broken install that doesn't have QPC and still depends on timeGetTime(). Fixes #4870.		2021-11-01 14:28:00 -04:00
