Planning for

There once was something called "Project Butter" for Android and
I would like to see something similar for JavaFX too. The goal should
be to make all user interactions with a JavaFX GUI as butter-smooth
as users expect them to be and as you can observe them in native
software. More specifically I'd like to see:

- general SG/CSS performance improvements
- more accurate rendering (double vs. float)
- use multi-threaded rendering with marlin renderer
- improved scrolling on touch devices
- hw-accellerated shifting of rectangular regions of a canvas
- better integration of external rendering engines into JavaFX (OpenGL, 
Media players, ...)
