Method: Pixelart::Image.subclasses

Defined in:
lib/pixelart/image.rb

.subclasses ⇒ Object

keep track of all (inherited) subclasses via inherited hook

change/rename to descendants - why? why not?

note about rails (activesupport?)

If you use rails >= 3, you have two options in place.
  Use .descendants if you want more than one level depth of children classes,
  or use .subclasses for the first level of child classes.
