Proportional rectangles

A rectangle, especially also as a container for an image or logo, can always keep its height-to-width proportion if the new property "proportional" is set:

(Image 1: Proportional rectangle)

If one value is changed, the other changes accordingly. This also works graphically when a rectangle is drawn at the corner or the side:

This is especially interesting for rectangles with logos or for images on rectangles in reverse engineering. The feature is available from V31.
