QuickerGraf 1.0 was released together with a performance benchmark
that compares the speed of various operations with QuickerGraf on and
off.  Timings are reported as percentages:

	(time without QuickerGraf)/(time with QuickerGraf) * 100%

Figures over 100% indicate an improvement due to QuickerGraf and
figures below 100% indicate a detriment due to QuickerGraf.  For
example, a result of 2441% shows that QuickerGraf is more than 24
times as fast as native QuickDraw for that particular operation in
that particular mode.

Since reports have varied as to whether QuickerGraf is beneficial in
any mode but 8-bit color, I ran the benchmark in every mode available.
Here are the results:

Test:                              Colors: 256    16     4     2
simple pixel pattern fill, no clipping     319%  100%  100%  102%
simple pixel pattern fill, region clipped  334%  243%  196%  150%
fill oval, unclipped, simple pattern       251%  173%  141%  118%
fill roundrect, unclipped, simple pattern  291%  201%  163%  133%
unclipped, unmapped, copy mode copybits    170%   99%  101%   97%
copybits with color mapping                310%   99%   99%  239%
1 to 8 copybits, no clipping               196%   98%   98%  100%
addover fill mode, simple pattern         1088%  100%  100%  100%
blend fill mode, simple pattern           2441%  100%  100%  100%
transparent fill mode, simple pattern      924%   99%   99%  100%
hilite mode, region clipped                258%   99%  100%  120%

     On two occasions I have been asked, "Pray, Mr. Babbage, if you put
     into the machine wrong figures, will the right answers come out?"
