I am the superclass for all separate parts of the Balloon 3D engine. I define the basic interface each part of the engine must respond to.

Instance variables:
engine <B3DRenderEngine> The 3D engine I am associated with

	private
	setEngine:

	processing
	processIndexedLines: processIndexedQuads: processIndexedTriangles: processLineLoop: processLines: processPoints: processPolygon: processVertexBuffer:

	instance creation
	engine: new

	testing
	isAvailable isAvailableFor:

	initialize	top
	destroy Destroy all resources temporarily assigned to the receiver
	flush Flush all pending operations
	initialize
	reset

	private	top
	setEngine:

	processing	top
	processIndexedLines: Process an indexed line set
	processIndexedQuads: Process an indexed quad set
	processIndexedTriangles: Process an indexed triangle set
	processLineLoop: Process a closed line defined by the vertex buffer
	processLines: Process a series of lines defined by each two points the vertex buffer
	processPoints: Process a series of points defined by the vertex buffer
	processPolygon: Process a polygon defined by the vertex buffer
	processVertexBuffer: Process the given vertex buffer in this part of the engine.

	class initialization	top
	initialize B3DEnginePart initialize

	instance creation	top
	engine:
	new Answer a new instance of the receiver (which is a class) with no indexable variables. Fail if the class is indexable.

	testing	top
	isAvailable Return true if this part of the engine is available
	isAvailableFor: Return true if this part of the engine is available for the given output medium
