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

1. Make it possible to enable/disable DEPTH test when rendering to a Screen
2. Using this, remove the 'Root' Node from StarWars.

A lot of different fixes.

A lot of issues still there:

1) if we only render part of the tree, tree isomorphism will sometimes not work correctly
2) when we change Effects that are inside Trees mid-render, even if we detach() the affected parts of the Tree first, for the last frame the new Effects will be used...

New, cleaner way to create/destroy DistortedSurfaces.

Serious regression in StarWars (crashes!). Looks like the Node's internal FBO is being deleted and not re-created in time.

Change the the render() API!

THis introduces some regressions with the Effects3D app.

Preparation for change of the render API.

Minor

Simplify yesterday's refactoring.

Major: change of API.

Split DFramebuffer into Framebuffer and Screen; introduce the 'DistortedInputSurface' and 'DistortedOutputSurface' interfaces.

Introduce Renderable to the Tree.

Fix the MultiBlur regression

progress with DistortedRenderable.

This introduces a regression with MultiBlur!

progress with DistortedRenderable

Introduce DistortedRenderable, a base class for Texture and Framebuffer
