    perf: Print ticks as well as ms in output.
    
    The ticks value is a bit more reliable since it won't exhibit
    variation due to estimating the CPU frequency like the ms value
    will.

    perf: Change minimum size of paint test to 256
    
    The paint tests at sizes less than 256 were just too fast to be
    significant.
