Distorted Android

Bugfix in EffectQueues: if we interpolate something, then stop and again start interpolating, it used to use the old position (position from the moment when we stopped interpolating!) during the first run after the resume. Fix that.

Minor

A Lot of fixes for the issues uncovered by Olimpic.

Still at least 1 known issue: sometimes, when we re-add a Surface, some garbage pops up on the screen for a brief split second. Visible in Olimpic.

a few lame fixes for the issues uncovered by Olimpic but it is still wrong

fix for the first issue uncovered by the new Olimpic.

Introduce 3 types of Surfaces: System, Tree, User

Do not add Screen to the Surface lists.

Fix OutputSurface.resize(): before it couldn't be called mid-render.

- workaround for the issue with flashing in StarWars
- return number of objects rendered from OutputSurface.render() and use this in Olympic
- rework tree isomorphism so that it now works even if we don't render the whole tree (and also we don't have to reset() the Tree anymore!)...

Fix issue with Blur / Multiblur apps
