Can we use thingCount instead of numThings? Also, why size_t?

[brianderson, 2012/10/04 20:11:59]

Sure, will make it consistent.
Should probably use uint64_t instead.  I used size_t so we could get very high
counts, but size_t is platform dependent and isn't always a 64 bit unsigned int.

     double totalPaintTimeInSeconds;
     double totalRasterizeTimeInSeconds;
     double totalCommitTimeInSeconds;
     size_t totalCommitCount;
     size_t numImplThreadScrolls;
     size_t numMainThreadScrolls;
