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
Minor improvements in DistortedTexture.
Beginnings of split of DistortedObject into two separate classes: DistortedEffectQueues and DistortedTexture.
Still does not compile, but pushing already.
