Algorithm ideas/todo list

[ericvoorhis]

I'm making a general issue to keep track of some ideas I don't want to lose before getting to work on pixel shifting.

• Pixel Propagation
• Implement my version of ChannelDrift but call it something different
• Implement energy function and use for seam carving and pixel sorting
• Create set of sub-algorithms that mimic marble paint algorithm
• zig zag stack (very useless name I know, but I can explain if you want. It's only here as a reminder)
• Add rotation to algorithms
