Eric,
this depends wholly on the implementation. Claris' products are very
inaccurate because they do constant conversion between units, which causes
things to move around from time to time. Also, many editing modes are
implemented inaccurate.

I tend to disagree. Try to scale a 3x3 pixel triangle to 30x30 and you'll
see the advantage of Vector over bitmap.

Again, this is a misperception based on inaccurate editing tools.

I have to disappoint you. The Mac is mostly object-oriented drawing
(=vector) on the inside. The Mac's built-in graphics format, PICT, is a
vector format.
>Last reason why bitmap rules, ok: scanning.
You have to use both bitmap and vector where appropriate. E.g. for
scripted graphics vector is much more convenient (see the SuperCard or Serf
example projects for proof). You can still use "bitmap" objects if you need
the advantages of bitmaps. It's a combination that's so cool (that's why
SuperPaint had such a huge following).

How are they painful? Just select the button and drag in one pixel to the
left. There's not much difference between that and using the "select" tool
to move a graphic one pixel. I don't get your point, it appears.
