wxgui saving 3d display to file contains save as dialog
When saving display to file from a 3D view, it grabs all window content area including any overlapping windows. In my case - the "Save As" dialog where output file name was chosen. The issue is that "Save As" dialog is not removed from rendering fast enough and thus wxgui map view window area still contains it. To reproduce the issue, one has to use slow enough system where updating screen area hasn't been finished before wxgui reads out its area contents for saving into a file.
