/*
	Some sample code for a horizontal paged UIScrollView with a gap between each image (which looks nicer). Note - not using contentInset, we want each page to fill the iPhone screen and the gap only to be visible when scrolling (like Photos.app).
	
	Taking the iPhone status bar into account - our viewport is 320x460
	Our UIScrollView is therefore set in Interface Builder to 340x460 with a -10 X offset (so it's larger than the viewport but still centred)
	
	Then we do the following...
