gemwin with multicontext does not react for [border 0(

with gemglutwindow.
at least here. under certain conditions. maybe dont take this very seriously.

ah well. with the new window-backends, not all options might be available for all dinwos-systems.
e.g. it seems that there's no way to force glut into creating a window without borders (although in 22cd8f4 i think i've done all there can be done...although it doesn't seem to work for me).

[gemglxwindow] should still work though.
