add hack to work around windows or AMD bullshit: 1px border around screen in fullscreen mode to avoid flickering monitors and corrupting taskbar due to gamer speedhacks getting activated which actually put your system in fullscreen mode without us having asked for it. This could be turned into an option, if anyone notices.

//Work around an AMD driver bug in >= vista:
//It seems windows will activate opengl fullscreen mode when a GL control is occupying the exact space of a screen (0,0 and dimensions=screensize)
//AMD cards manifest a problem under these circumstances, flickering other monitors.
//It isnt clear whether nvidia cards are failing to employ this optimization, or just not flickering.
//(this could be determined with more work; other side affects of the fullscreen mode include: corrupted taskbar, no modal boxes on top of GL control, no screenshots)
//At any rate, we can solve this by adding a 1px black border around the GL control, and this is a really easy way.
//Please note: It is important to do this before resizing things, otherwise momentarily a GL control without WS_BORDER will be at the magic dimensions and cause the flakeout
