Way to expand or crop the canvass

## Requested feature

In MS Paint, if I want to make the canvass bigger or smaller I can grab the corner or side of the canvass and expand it or reduce it.  I can't find any way of doing this in drawing.  



## Use case

I would use this, for example, to combine two photos into one - expand the canvass in one photo, and paste the second photo in.
