The rectangle will be drawn using the current shape properties. To determine the current shape properties, call LRasterPaint::GetProperty. To set or change the current shape properties, call LRasterPaint::SetProperty. For more information on the shape properties, refer to the PAINTSHAPE structure.
If UserDC is not NULL, the toolkit will paint the rectangle on the specified device context. If UserDC is NULL, the rectangle will not be painted on a device context.
If the UserDC is not NULL, the user should set the DC boundaries before calling this function, by calling LRasterPaint::SetDCExtents.
If a bitmap has been set using the LRasterPaint::SetMetrics function, the rectangle will be drawn on the specified bitmap. If UserDC is not NULL and a bitmap has been set using the LRasterPaint::SetMetrics function, then the rectangle will be drawn to both the device context and the bitmap.
