An Leadtools.Drawing.RasterPaintProperties structure which controls the painting of item images in this control.
If the item image has a transparent color (RasterImage.Transparent is set to true) then the RasterImageList control will automatically revert to the GDI+ paint engine. It will temporarily set the RasterPaintProperties.PaintEngine value of the PaintProperties property to RasterPaintEngine.GdiPlus when drawing this item.
