Review request for Plasma.


Summary
-------

this is a generalization of mask() and adds the function alphaMask() that is kinda like the mask but returns a QPixmap instead, this is useful if one wants to compose an image with the alpha layer of the frame, being the frame pixmap itself or a nother frame with the "mask-" prefix.
now i'm not sure if it's ok putting it  up now or after the freeze and if it should be public or private, since the only use i have now is some experiments i'm doing for themes in 4.3 (hint: http://www.notmart.org/misc/plasma-overlay.ogv) but i feel it could be useful even now.
