FYI: Found mouse gesture in Opera Browser

[Casper]

Hey guys, anyone who uses Opera as their desktop browser will know about its great feature "mouse gestures".
Now in the Opera mobile - on our phones - I'm sure alot (if not all) have come across the 'back' (diagonal from bottom right to top left or from top right to bottom left) & 'forward' (diagonal from bottom left to top right or from top left to bottom right) mouse gestures; you most likely came across it by chance.
I've found a new one..namely, zoom in & out!:
It's a diagonal movement from top to bottom and back up for zoom out.
For zoom in it's a diagonal movement from bottom to top and back down.
It doesn't matter from which direction

Maybe it's been found already, or I'm the only one who didn't know about it. But there it is.

Yes, it does. but only by 10%.
I would like something like the one in Picsel viewer.
