refactoring the feedFrame/renderFrame/getTexture flow to make a more
clever use of memory and autorelease pools
started implementing CVFilter
(on the way of having CoreImage filters usable from javascript)
- Separating view logic from the real layer implementations
(so layers can be created programmatically and associated to a
view only if/when necessary)
- Separating the c++ glue classes from their related cocoa implementations
It Can be changed through the preferences panel (WIP)
(started implementation for a screen-keyboard-listener
to capture keystrokes acting like cocoa-based keyboard
controller)
- per-layer filter parameters are now restored correctly when moving the
filterpanel between different layers
- Various fixes and improvements in CVF0rLayer as well.
- The FilterPanel now doesn't disappear when selecting a new filter.
- Introduced the preliminary logic necessary to access geometry layers
created through javascript
