// Class : PStatGPUTimer
// Description : This is a special type of PStatTimer that also
// uses a timer query on the GSG to measure how long
// a task actually takes to execute on the GPU, rather
// than how long it took for the API commands to be
// queued up.
//
// This class may only be used on the draw thread.
//
// At present, it tracks both the CPU time (like a
// regular PStatTimer does) and the GPU time, which
// is recorded using a special PStatThread.
