[reportlab-users] KeepInFrame.drawOn() working?

Is that a statement along the lines of "Better don't do that!
We would be surprised if that worked..."?

As I showed in my code you can add information about width,
height and content to a KeepInFrame instance. I found you can
also add the surroundigng canvas object as instance variable.

And after doing this in some cases it *does* work as expected.
So, it might only need a bit of work to get it work consistent-
ly... Sorry for my old consistency "disease" showing up again!
