OK, translucent, continuous borders it is -- no marching, no
dashing...and to think MacPaint did this effortlessly in 1984? This
is progress? ;-)
Thx for the tips,
Peter.

Yes. What, you want XOR mode too? :) That's another thing that doesn't work
well cross-platform (and isn't supported by Quartz at all, nor did it ever work
well on, say, a gray image.)

No, not that I can think of. An Object2D isn't a CoreGraphics object, though
it may be rendered as one -- rather, it's a REAL Software invention, which is
internally exactly the same on all platforms. It doesn't get converted into
something platform-specific until rendering, but you have no way to hook into
or extend it at that point.

Hi Steve,
I've tinkered with things like this in the past -- though for a somewhat
different purpose (in one case, a programming environment for kids; in another,
a set of rules for a Myst-like adventure game). If you'd like a hand
developing this, I'd be happy to consult on it.
Best,
- Joe
