[PD] array zoom

[João Pais]

Hi,

in case there are still GUI changes being made, I had a suggestion for
arrays: a check box to decide if the array should be displayed outside of
the canvas or not (and adding a message control to it as well).

By making canvas control independent of the size of the array, it would be
possible to "zoom" in on an array. For example, if an array has 100
points, by making the canvas display only points 20 to 40 it would be
possible to show only part of the whole thing. Presently, the whole array
is always displayed, even if it goes outside of the canvas.

This "zoom" could also be done with some copying, and a 2nd array for the
display, etc. (or even with a general purpose abstraction for it). But it
can be much simpler if it could be done on the original thing.

Best,

João
