Updated to work in 5.8 & golfed some

It's pure perl, string/warnings compliant, and has been tested on 5.8.8 and 5.12.4 and on windows, ubuntu & centos, so i'm fairly confident it works everywhere - let me know if it doesn't

  • Image::Dot has a 1x1 dot png, which I used as the initial approach and extended.
  • This java PNG encoder by Christian Fröschlin was useful to confirm I was on the right track.

What's missing?

• thorns
• I might try and include BooK's encoder to actually produce compressed png's (without too much trouble)
• I'd like to add some sort of anti-aliasing or more likely hq3x
• It would be interesting to complete the png generation by adding filtering
