tdf#82009 TreeList move painting of drag target into Paint func.
When we drag a entry in TreeListBox, we execute a PaintDDCursor which paints a "cursor" of a possible drag target (for example to show where the entry will be moved to if we want to change the order). The problem with this fuction is that it paints a line directlly at that location, and that it uses invert raster operation to draw a line. So to hide the line it just needs to draw again. On MacOS this invertion causes a problem and draws the whole area black, which is the cause of this bug. So instead of inverting the drawing of the drag target cursor has now been moved into the main Paint method, where it redraws the whole entry, and if present, also the drag target cursor. This means that all we need to do is Invalidate the entry, which then just gets redrawn in a normal Paint pass. One exception is still MacOS, which doesn't invalidate the entry, but redraws the entry directly. DnD is MacOS is a bit different as it is not async (if I understand correctly) so the invalidate has no effect.
