Subject: Add support for scrolling left and right in the canvas window. Ctrl+LeftScroll zooms... 
X-Git-Url: https://git.pterodactylus.net/?a=commitdiff_plain;h=f9816d45921e9b4d4b98204bff76f94d9c58cd19;p=synfig.git

Add support for scrolling left and right in the canvas window. Ctrl+LeftScroll zooms out, Ctrl+RightScroll zooms in. Shift works the opposite to up-down.
