Win32/Xbox360 implementation of the Time::Timer class. Uses

the QueryPerformanceCounter() functions.

@todo solve multiprocessor issues of QueryPerformanceCounter()
|
||
(different processors may return different PerformanceFrequency
|
||
values, thus, threads should be prevented from switching between
|
||
processors with thread affinities).
