Further simplify ObjectType
Major change: separate the notion of a TwistyObject and its Node. Now,
1) the Node stays when we change objects (this makes transitions faster)2) it's possible to just create an Object without adding it to the Screen (now app needs to explicitly create the Node and add it to its Screen itself)
- remove the retarded NODE_RATIO from TwistyObject- more correctly estimate Cuboid's 'realSize' as an average of their 3 sizes.
Relax objectlib's requirements: it can be displayed not only on top of a DistortedScreen, but any DistortedFramebuffer.
No, move the object afterall. Why? See in Tutorials - a moved node has the right side missing.
Improve 'off-center' objects: move the node, not the object!This simplifies the Effects and makes them more correct (glow!)
off-center objects: finished.
progress with off-center objects.
1) introduce possibility to move objects, i.e. display them not in the middle of the screen (not fully functional yet)2) do away with unneeded any more interface 'EffectController' - since ObjectPreRender is the only implementation now.
Remove the 'setupObject()' redundant API.
Bugfix: we shouldn't be calling TwsityObject.solve() directly from the app, only through ObjectControl.solveOnly().
Simplifications
Move yet more code to objectlib.
