onPause(): fix StarWars

Bugfix: only add EffectListener ONCE!

Some improvements for StarWars's behaviour after onPause(), but it doesn't really work yet.

Remaining 'onPause-buggy' apps: StarWars, Save.

Attempt to bring DTexture and DFramebuffer closer together.

Minor.

Speed up ObjectTree: we no longer have to traverse the whole tree before rendering to mark everything as not-rendered-yet.

Change of API in DistortedFramebuffer.

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.

Complete the split DistortedObject -> (DistortedTexture,DistortedEffectQueue)

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.

Some fixes for the recent API change

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

Fix parallel projection.

The EffectQueues are now totally independent of the size of the underlying Bitmap.

Minor

Some speedup in CubesGrid

Fix a long-standing buf in CubesGrid (incorrect Grid in case of 5x5 11111 11011 10101 11011 11111)

Chasing a bug in DistortedCubesGrid.markRegions() ( visible with a 5x5 grid, 11111 11011 10101 11011 11111 ) - some side edges are missing. markRegions computes incorrect number of side Segments in this case.
