Hi,

I'm using a Ctrl as a container for drawing. However, when I resize the window, drawings in the 'pane' become stretched and no longer on a 1:1 (or whatever i:j initial constant) x:y aspect.

This is especially obvious because I'm drawing text into the Ctrl as well, in a Drawing object. I suppose either I can forcibly scale the Drawing object to a sensible ratio before painting it, or I could find a way to dynamically resize the parent Ctrl to match the ratio of the minimum x/y value.

Is there an easy way to do this? I couldn't find a function to override in Ctrl that will allow me to adjust things when resizing - I've tried overriding SetRect and SetFrameRect in their various incarnations, but they don't seem to be called.
