Marco Martin aa33e4ade0 a new hint: hint-compose-over-border
the centr element will be rendered as big as the image, cropped with the alpha mask and the borderssuperimposed over it.
slightly slower but it's the only way to have radial gradients in the center element and have them rendered in a correct way
