Public Member Functions inherited from Gondwana.Drawing.IDrawable
RectangleF	GetDrawLocationScreen (View view)
	Computes the object's destination rectangle in SCREEN pixels for rendering on the Backbuffer, using the provided View to project from world-space.
void	Draw (BackbufferBase backbuffer, RectangleF destRectScreen)
	Draws the object to the Backbuffer using the provided SCREEN-space destination rectangle. The rectangle is assumed to already be projected into screen-space; no world-to-screen conversion should occur within this method.

Detailed Description

Defines a movable direct drawable that may be owned by a DirectComposite.

The interface provides the coordinate target and visual operations required for recursive composition without requiring DirectComposite to recognize concrete child types.

Container implementations should apply visibility, Z-order, opacity, and fade operations recursively to their descendants.
