...and I had a random idea (so not necessarily practical) that since we have "metrics" as an object, I wonder if a built in feature to draw these metrics on the canvas - kind of a developer guidelines to be used temporarily during prototyping. Something like...

which would be commented out of production code.


Now what I'm really interested in is a zoomable image window, preferably using the mouse wheel.�� Any chance such example if available somewhere?
