Announce: ctx2png

I want to announce first version of ctx2png. Ctx2Png is an addon to the GRX graphics library. It loads/saves a context from/to a PNG file. PNG is a lost-less compressed graphics format. It have lots of features, like the ability to handle an alpha channel. You can read more about the PNG format in http://www.libpng.org/pub/png/libpng.html The routines are not very efficient, but they work.
