Distorted Android

Minor.

Major:

1) in the Library, fix the fact that some applications (those that were creating their DistortedSurface objects outside of onSurfaceCreated or onSurfaceChanged) would not render after the activity went to background (press POWER to see that).
2) in the Apps, call the new 'Distorted.onPause()' API to fix the above problem...

Upgrade from GLSL 1.00 to GLSL 3.00 ES
Introduce separate BLUR1 and BLUR2 shaders, the second one marging (writing to gl_FragDepth still does not work)

Introduce Effects.blitPriv() (faster than previous drawNoEffectsPriv)

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.

Introduce 3 types of Surfaces: System, Tree, User

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

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.

Preparation for change of the render API.

Simplify yesterday's refactoring.

Major: change of API.

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

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

Minor

Try using OpenGL ES 3.0 everywhere (but if device does not support it, try creating 2.0 context - this is important because of the emulator!)

rename all the 'grid' variables to 'mesh'.

Rename Grid to Mesh

Simplify DistortedTexture.

Minor.

New DistortedProgram class.

Javadoc

Change of names.

Minor.

Major restructuring with DistortedTexture. One now is able to create Textures anywhere, even from a thread which does not hold the OpenGL context. Same for DistortedFramebuffers.

Minor.

Hide the 'depth' of a DistortedTexture inside the library, so users do not get exposed to this weirdness.

Minor

Minor improvements in DistortedTexture.

Beginnings of split of DistortedObject into two separate classes: DistortedEffectQueues and DistortedTexture.

Still does not compile, but pushing already.
