shrink

Description:

public unowned RoundedRect? shrink (float top, float right, float bottom, float left)

Shrinks (or grows) a rounded rectangle by moving the 4 sides according to the offsets given.

The corner radii will be changed in a way that tries to keep the center of the corner circle intact. This emulates CSS behavior.

This function also works for growing rounded rectangles if you pass negative values for the top, right, bottom or left.
