/*	OOConvertCubeMapToLatLong
	
	Given an RGBA pixmap containing a cube map texture, convert it to a latlong
	texture of (height * 2) by height pixels. The texture is also flipped, to
	account for Oolite texture coordianate conventions.
	
	The source pix map must have four components and be six times as high as
	it is wide.
	
	2 x 2 pixel supersampling is used.
