DGA2, 800x600 16 bpp.
$ ./misc/cmplog.pl tests/noaccel.log tests/accel.log
(note the order)
before -> after
putpixel() = 96% -> 95%
hline() = 41% -> 42%
vline() = 69% -> 78%
line() = 16% -> 16%
rectfill() = 273% -> 271%
circle() = 21% -> 21%
circlefill() = 22% -> 51%
ellipse() = 28% -> 28%
ellipsefill() = 20% -> 49%
arc() = 20% -> 21%
triangle() = 18% -> 46%
Improvements for circlefill, ellipsefill and triangle, but otherwise
no effect.
