Syntax
public class GorgonOrthoCamera : GorgonCameraCommon, IGorgonGraphicsObject, IGorgonNamedObject
Remarks

This camera performs 2D projection of sprites and other renderables on to a target. By default, the camera will use absolute screen space coordinates e.g. 160x120 will be the center of a 320x240 render target. The user may define their own coordinate system to apply to the projection.
