[PD-dev] Window position fix lost

Hey all

Back in February IOhannes commited a fix for window position on X11. It fixed all the window jumping troubles I had before and that I tried to address by manually adjusting windowframex and windowframey in pd- gui.tcl.

Soon after, the fix doesn't have any effect anymore. With current master the situation even worsened. When 'vis 0' and 'vis 1' a canvas, the window jumps down by a significant amount of pixels (> 30). And this behaviour can't be addressed anymore by my manual fix described above.

The last good version I know: 7a8cce12 From this on jumping occurs:  dfbfc754

Attached patch illustrates the jumping window on X11 (tested on Ubuntu 16.04).

On macOS, I can't reproduce the issue, the window stays in place.
