/**
 * Abstract morphed panel to be used in TopLayerPanel.
 * Screen width and height are to be supplied when declared in the top layer panel
 * Others are to be declared by panels deriving from this
 *
 * To make sure morph movements don't look weird:
 *   - Follow the convention of having points start from bottom-middle and go clockwise
 *   - Make sure the number of points is "balanced" in all directions
 *     - Tip: Sometimes symmetry is not enough. Try to have more intermediate points if ones you have are too spaced out and act funny.
