interactive-adjust-resize in pasteboard%

This method is called during interactive resizing of a snip to preprocess the user-determined snip size. The snip and mouse-determined height and width are passed into the method (boxed); the resulting height and width are used for graphical feedback to the user during resizing.

The actual mouse coordinates are first sent through interactive-adjust-mouse before determining the sizes passed into this method.
