Description

Reading a tile from a PNG file currently means reading the entire image and then cropping out the desired rectangle. Now that we're no longer using ImageIO, I think it will be possible to be a little smarter, at least in the case of non-interlaced (and possibly unfiltered?) images.

See for example ​http://xkcd.com/980/sources/money_huge.png
