Drawing functions, zoom and automatic scrollbars

The option "Automatic scrollbars and zoom", available on a Image control, is incompatible with dStartDrawing. If this option is used on the Image control, the display performed by dStartDrawing is fixed in the control. The zoom is also fixed. The standard behavior is restored during the call to dEndDrawing.
The same effect can be noticed with dPixelColor and dRotation.
