Minimum screen size check - how important ?

In winOGLVideo.cc, there's a check to make sure the window is not smaller than 640x480:

if ( newRes.w < 640 || newRes.h < 480 )
{
Con::warnf( ConsoleLogEntry::General, "OpenGLDevice::setScreenMode -- can't go smaller than 640x480!" );
return false;
}

- any ideas how important this is ?

i overrode it for a significantly smaller resolution and it worked fine in Windowed mode,
which is where i want it.

the only problems i see are:

*dialogs get clipped, but that's fine, we can deal

* when going to full-screen you have to handle the situation where the display device doesn't support the requested size.


- any others ?
