Defines a transparent win control class. The control provides a base class for controls that wrap Windows screen objects but perform their own rendering. Instances of this class can receive focus and serve as containers.
Classes of controls that perform their own screen rendering and do not need the features of TWinControl should be descendants of RSGdiPlusCtrls.TRSCustomTransparentGraphicControl instead of TRSCustomTransparentControl. TRSCustomTransparentGraphicControl objects can render themselves with less overhead, because they do not have underlying Windows screen objects.
TRSCustomTransparentGraphicControl objects have a Paint method, which is called whenever the control needs to render its image. Custom controls paint themselves using the Canvas property.
