treeview: column drop target visualization broken
Last modified: 2014-09-08 02:28:10 UTC
We try to render arrows or a rectangle at the place where the dragged column will snap in. The rendering is broken, it appears as a solid white rectangle. The arrows don't show up at all.

This patch is not complete, but it gets some of the rendering back to working.
some further findings: It appears shapes are broken for child windows. If I make the drag_highlight_window a toplevel for the 'original position' case as it already is for the arrow cases, then I do get the correct rectangle shape. Still need to draw that window in gtk_tree_view_draw, and there's some issue where the window does not show up.
