Shapes are sets of connected lines. Rectangle, Ellipse & Bezier are all represented by this class. In fact, the Bezier/Rectangle/Ellipse constructors simply call a shape constructor and plots the appropriate points. Additionally, this class can be used alone to generate any shape you like, most notably polygons.

For Bezier, every 4 points you plot represent one segment...
   1 = origin
   2 = origin handle
   3 = destination handle
   4 = destination
The separation between segment a's destination and segment b's origin adds a little more flexibility than Photoshop where they are forced to the same value.

Shape( )
» Shape with no points, plot some

Rectangle( left:number, top:number, right:number, bottom:number )
» Pre-builds Rectangle shape at specified coordinates

Ellipse( left:number, top:number, right:number, bottom:number )
» Pre-builds Elliptical shape, including circles, whose bounding box is the specified parameters

Bezier( )
» A bezier curve with no points, plot some

fillmode:number
» get and set the fillmode used when drawing ( SEE : Shape Fillmodes )

plot( x:number, y:number )
» add a point to the shape

offset( dx:number, dy:number )
» offset all coordinates by dx and dy
