sl@0: RDirectGdiImageTarget is a handle to a DirectGDI adaptation-specific resource which 
sl@0: abstracts the image-based rendering target. The main intention in creating this resource 
sl@0: is to allow a global sharable image resource (RSgImage) to be used as a target of 
sl@0: DirectGDI rendering. For example, in a DirectGDI adaptation where OpenVG is used to 
sl@0: implement DirectGDI functionality, the creation of RDirectGdiImageTarget may be associated 
sl@0: with the creation of an underlying EGL surface from the given RSgImage. This handle class 
sl@0: and its DirectGDI adaptation-specific resource are non-sharable and local within the 
sl@0: creating thread.
sl@0: 
sl@0: This class is part of a generic layer and will forward any request to the CDirectGdiDriver
sl@0: singleton for the calling thread.
sl@0: 
sl@0: CDirectGdiContext is activated on an RDirectGdiImageTarget. This causes all subsequent
sl@0: context drawing operations to to draw to the image resource referred to by the 
sl@0: RDirectGdiImageTarget.
