Can anyone tell me which would result in a faster stroke of a complex
path, using a pattern or a dash? I'm changing our marching ants from
QD to Quartz. The QD code xor'd 8 different patterns progressively.
Switching to Quartz I used a {2,2} dash and increment the phase by 1
each time. This results in very odd animation when running on a
450MHz G3. The bottom third or so of the path draws correctly each
time (marching along nicely), but the upper 2/3 or so will sort of
jump around, or seem to just toggle between 2 different dash phases.
Would stroking with a pattern be any faster? I'll be drawing the
pattern to mimmic the QD patterns, which were 45° 4-pixel alternating
black/white lines, so I'll probably use something like this as my
pattern draw code: BeginPath, (MoveToPoint, LineToPoint) * 3,
StrokePath.
