I just checked MacDraw II and Canvas 2.0 -- much to my chagrin,
rotated text seems to be transferred easily between the programs using
picture comments.

On the other hand, Canvas 2.0 does screw up rotation.  Once an item is
rotated, it is represented on the screen by a bitmap.  Subsequent
rotations just spin the bitmap, making the item illegible upon the
second rotation.  "Zoom In" does not enhance the legibility of a
rotated item.  I could also swear that there are cases in Canvas 2.0
when a rotated item was permanently converted into a bitmap without my
consent, but I cannot reproduce this problem.

I guess it takes more than just an interchange format to get
developers to implement rotation correctly.  Or Maybe Canvas is just a
kluge -- I'm beginning to think (more and more) that this is the
actual answer.
