	4 Subject: [PATCH] ratiofullscreen patch
	5
	6 Toggle fullscreen for a window while saving its ratio.
	7 Space left uncovered by a window may be set to be black or left
	8 transparent.
	9 The patch is intended to be used with old games which have miniscule
	10 window sizes and don't handle fullscreen correctly themselves.
	11 Smartborders patch (its modified resizeclient function) is a dependency
	12 of this patch.
