Distorted Android

Rename MeshFlat MeshRectangles.

Simplify the way applications can get notifications when an effect finishes.

Now, instead of the 'DistortedEffects.(de)registerForNotifications()' 2 APIs, we call a single 'Effect.notifyWhenFinished()'.

Correct the Legal notice.

Rename all the classes that are not exported to application to 'Internal'

Massive: make the coordinate system agree with that of OpenGL (i.e. invert the Y axis).

Make the Fragment effects truly 3D: change their 4D 'region' into a 3D 'center' (a point in 3D) and 3D 'region' (which is now a set of 3 radii defining an ellipsoid around the center)

Also corresponding changes to the applications.

Redefine the Vertex Region from (x,y,r,unused) to (x,y,z,r). This takes into account the 'Z', which makes it possible to warp only one side of a 3D Mesh like Sphere.

Also corresponding changes in applications.

Fully move the Meshes to their own package.

Move all the knowledge about Vertex and Fragment effects to their respective classes.

Change of API: move setting the EGL context back to the APP.

Fix 'EffectQueue' APP. Now 30 out of 31 APPs work.

Some progress with Effect classes.

11 apps compile now.

Some progress with Effect classes.

10 apps compile now.

Progress with support for Effect classes.

Simplify setting up DistortedScreen.

Revert "Major refactoring: convert the Matrix Effects to be independent of the resolution of the surface we render to."

This reverts commit d79a56d3bc6cc7a22b21abeb180353a1818bd6ad.

Major refactoring: convert the Matrix Effects to be independent of the resolution of the surface we render to.

Re-write the first 15 apps to work with this.

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...

It now automatically chooses OpenGL ES 2.0 and GLSL 100 or OpenGL ES 3.0 and GLSL 300.

Postprocessing effects will not work on OpenGL ES 2.0 contexts.

New 'glClearColor' and 'glClearDepthf' APIs in OutputSurface. This fixes the 'transparency' regressions from last commit.

Speed up shaders (both compilation and execution) by explicitly enabling only the needed effects.

Change the the render() API!

THis introduces some regressions with the Effects3D app.

Major: change of API.

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

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 Grid to Mesh

New DistortedProgram class.

Fix Lint warnings, correct a lot of comments, adjust EffectListener interface.

Fix a lot of Lint warnings in the apps.

Again change of API. Now instead of the 'DistortedEffects.draw() and DistortedTree.draw()' we have 'DistortedFramebuffer.renderTo()'

Change of names.

Change in the API: we always have to create a DistortedFramebuffer to render to.

onPause(): fix StarWars

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

Complete the split DistortedObject -> (DistortedTexture,DistortedEffectQueue)

Rename various classes; fix a bug in Around the World.

Major change in API: separate the GRID from DistortedObject; completely remove classes derived from DistortedObject.

Simplify SurfaceViews

Make the effect Center be always 3D.

Minor

Rename Effects2D to EffectQueue
