problem with painting nodes PaintTree with poUnbuffered in options and setMapMode...

[johnek123]

When using mapping mode - nodes draw in incorrect positions.

setMapMode       (image.canvas.handle, MM_ANISOTROPIC);
setWindowExtEx   (image.canvas.handle, 1, 1, nil);
setViewportExtEx (image.canvas.handle, 2, 2, nil);

treeview.paintTree (
                    image.canvas,
                    rect  (0, 0, image.width, 100),
                    point (0, 0),
                    [poGridLines, poUnbuffered],
                    pfDevice
                    );

I'm not sure if the painting code of virtual treeview is prepared for other map modes than MM_TEXT. Please attach your sample project as ZIP file.

Sorry, I never worked with poUnbuffered so far and have no idea how to fix this. This all looks like a corner case to me. It is somehow related to #579.
