public abstract class Canvas
extends javax.swing.JPanel
implements java.awt.event.ActionListener, edu.cmu.sphinx.instrumentation.Resetable

a canvas that contains @see{Tile}s which can be selected, moved around, placed, etc. tiles within the canvas live in a logical coordinate system, which is mapped to screen pixels using the final SCALE variable. the canvas has a size of RELATIVE_WIDTH * RELATIVE_HEIGHT a tile in a canvas can be selected and this tile can then be moved around
