Defines a transparent graphic control class. The control provides a base class for simple, lightweight, transparent, controls that do not need the ability to accept keyboard input or contain other controls. Since lightweight controls do not wrap Windows screen objects, they are faster and user fewer resources than controls based on TWinControl.
TRSCustomTransparentGraphicControl provides a Canvas property for access to the control's drawing surface and a virtual Paint method called in response to paint requests received by the parent control.
