// points: StencilPoints
//		Points is an array of objects that make up the

//		that is 100x100 and at x:10 and y:10 would look like:
//		[{x:10,y:10}, {x:110, y:10}, {x:110, y:110}, {x:10, y:110}]
//		Points go clockwise from the top left. In the case of Paths,
//		they would go in the order that the Stencil would be drawn.
//		Always when the points Array is set, a data Object is created
//		as well. So never set points directly, always use setPoints().
//
//		See: setPoints()
points:[],

// data: StencilData
//		A data object typically (but not always) resembles the data
//		that is used to create the dojox.gfx Shape. The same Rect
//		example shown in points above would look like:
//		{x:10, y:10, width:100, height:100}
//		And an Ellipse with the same coordinates:
//		{cx:55, cy:55, rx:50, ry:50}
//		The only Stencil that does not support data (at this time)
//		is the Path. While x1,x2,x3... culd be used in a data object
//		it doesn't provide much benefit.
//		Always when a data object is set, a set of points is created
//		as well. So never set data directly, always use setData().
//
//		See: setData()
data:null,

// marginZero [readonly] Number
//		How closely shape can get to y:0 or x:0. Less than zero has
//		bugs in VML. This is set with defaults, and should be equal

//		Whether the Stencil can draw with a mouse drag or can just
