Different interpolations between Keyframes

[linusha]

In addition to easings, which control the "speed" of an animation, we could also think about different interpolations between them. This might benefit already some of the points mentioned in #69:

• quadratic?
• cubic?
• circle
• log?

Could also entail Bezier Curves.

for mouse interaction it would not be interesting to make free hand paintings but to move points and define curves with it

http://pomax.github.io/bezierjs - drawing code needs to be added, supports cubic and quadratic curves
https://github.com/jsplumb/jsBezier - no drawing interface, hard codes cubic curves

Since this seems to be the Bezier-Curves ticket now I will close #69 as adding Bezier Curves of course requires an accompanying interface. This ticket will probably need to be split up when we decide to actually tackle it.
