i can't for the life of me figure out how to mask/clip a dragged proxy image (done via DragManager) to a Canvas. dragging works plenty fine except the dragged image can be dragged off the Canvas (it can't be dropped though) which is kind of annoying.
i've tried adding masks to the original Image (which has no effect) as well as to the proxy image, which "works" except that you can't drop the image anywhere. i think i have some kind of misconception about when/where to place a mask or simply you can't mask/clip a proxy image. any guidance is most welcome. thanks.
