Rotate/flip layers

[mrbig]

Hi, I've added the feature to be able to rotate/flip layers. Please take a look at my code, and if you like it, then I'll clean this up a bit before merge (updating documentation, tests, etc)

Does this work for animated GIF?

Hi, I've updated the Gif Engine also, did work for me as expected.

I still have a problem: order of actions could be important when combining rotation and flip, but the current parametrized bag implementation is unaware of that. So this might would need some changes down there also. For now rotation is always executed as first, resample as next, and flip as last.

Imagecraft project is started when my website need to manipulate avatars that users upload, so this is why I forgot to add rotate/flip features to imagecraft.

My code is very complex, especially the GIF part. I‘ve never thought someone could understand my code and add any new feature to it. Anyway, very great job, I have added you as an imagecraft collaborator, you can merge pull request yourself if you think everything is ok.

Also, to solve the order of actions problem, you can combine flip/rotate to one feature: transform(int $rotate, bool $flip), the image must rotate first, then flip.

Rotate would be a great feature, any chance this will get merged?
