Hi,
do you plan on adding button masks for gui buttons, so that we can have buttons that are only clickable on the desired areas?
Here's an example:

The button image is a circle, but the clickable area is actually a rectangle. Buttons can also have other different shapes, like cut off edges.
I guess the best way would be to add some kind of button mask, maybe an optional second image that contains information about the clickable/hover area (like white color => clickable, alpha=0 => gets ignored)
Thanks.
