We have bugs a) and b).

The way the question was asked begged for a yes/no answer, and was too general:

    "all this dragging/moving code" ....


The truth is likely to be somewhere between yes and no, since wx dictates much of the
event realm for a window of any kind, even either kind of GAL window, as far as scrolling
is concerned.  What one does in those event handlers is a slightly different topic.
(Clearly re-drawing is different.)

But the viewport abstraction I assume stays, and I think we still have bugs a) and b).
Maybe if the redrawing operation itself is the only difference, and can be abstracted,
then most of the contemplated bug fixing code can be re-used.

Since Maciej was not involved at the detail you and I were into the specifics of the
issue, and the question was too general, begging for a yes/no answer, I fear the two of
you have talked past each other, and I have to wonder if his answer to a general question
should be interpreted literally.

But I have already said that I think the bug is not urgent, since the user almost has to
be trying to break something.  It is however important in my opinion.
