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.
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.
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.
Hide the 'depth' of a DistortedTexture inside the library, so users do not get exposed to this weirdness.
Beginnings of split of DistortedObject into two separate classes: DistortedEffectQueues and DistortedTexture.
Still does not compile, but pushing already.
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.
remote unneeded 'static' variables and methods from the 'Dynamic' app
Improvements to the Dynamic app.
1. Attempt to deal with unstable Orthonormal Base in Dynamic class (so far unsuccessful)2. Improvements to the 'Dynamic' (and by necessity, 'MovingEffects') applications (to be able to debug the previous)
Further reduce the distortedObject's API - now only 26 methods, 1/4 of the 104 before the reorganization.
