Add support for fixed point graphs (enabled by default)

Browse Source 
Fixed point graphs are smaller because they don't include the decimal point. They're also faster to write. We need to apply a scale in order to have subpixel accuracy. The scale is specified by -fixedpointPrecisionScale <N> (default is 2)
- This improves perf report generation speed by ~15% and report size by 20%.
