Fixed bug 2101 - CWBackPixel causes weird window flickering on window resize

aBothe

I tried to experiment a bit with SDL2 and OpenGL today and noticed that something caused some weird flickering when resizing my nicely drawn SDL2/OpenGL window:
Just after resizing, the background went black and I had to let my OpenGL code redraw the contents..
However, after some hours spent with googling I found out that in OpenGL examples where this CWBackPixel flag was not used when creating X windows, there was no flickering while resizing the window.

See http://www.sbin.org/doc/Xlib/chapt_04.html @ "The Window Background" for more info.

           WMs each have their little quirks with that.  When you change the
jorgen@6899
   848
           size hints, they get a ConfigureNotify event with the
jorgen@6899
   849
           WM_NORMAL_SIZE_HINTS Atom.  They all save the hints then, but they
jorgen@6899

           don't all resize the window right away to enforce the new hints.

jorgen@6899
   854
            - A code-initiated move or resize

            - Hiding & showing window (Unmap & map)
slouken@6541
   856
jorgen@6899
   857
           The following move & resize seems to help a lot of WMs that didn't
jorgen@6899
   858
           properly update after the hints were changed. We don't do a
jorgen@6899
