+/** This is a test render stage used for integration testing extended bitmaps of  
+type 0x10285A78. This particular type of extended bitmap was created to test the 
+extended bitmap APIs added to CFbsBitGc (CreateExtendedBitmap(), ExtendedBitmapType() 
+and DataSize()) and also to test the extended bitmap rasterizer interface, CFbsRasterizer.
+The proprietary data contained in an extended bitmap of type 0x10285A78 defines
+the colours and stripe direction of a tricolour flag. 
+
+This render stage implements the MWsGraphicsContext interface so that it can intercept
+any drawing commands that draw an extended bitmap, any commands that draw a normal 
+bitmap are just passed through to the next renderstage (along with any commands that
+do not involve bitmaps at all).
+
+A CNvgRenderStage object is created by a CNvgRenderStageFactory.
