Dependencies
------------
For the png format libpng is required. For the jpg format libjpeg of libjpeg-turbo is required. The bmp format does not depend on anything, so you can output images without other libraries :D.
TODO
----
* Make output iterators
* Add alpha support (where possible)
* Some interface for parameters (eg. jpg quality)
* Add appropriate license
* Really make it a library (ie. restructure directories)
