Is there any way to get double precision drawing in appkit/
foundation? I ask because I am making a view that needs to be able to
handle *huge* sizes at pixel resolution (a hex editor), and 24 bits
of precision just doesn't cut it (I get artifacts after I scroll down
aways, and they get worse the further I go). Is there some double
version of the geometry structures (NSPoint, NSRect, etc)? Or do I
have to use Quartz / ATSUI?
The only solution I can think of is to redraw the whole view at once
even if only a small portion of it needs redrawing (which works, but
not very well).
Has anyone else encountered this problem and come up with a solution?
I didn't find much on cocoabuilder (only someone trying to make a
10,000 pixel view), but it is possible I am using the wrong search
terms. Any pointers?
Thanks,
Jonathan
