Order Independent Transparency. Does not work yet.

Disable blending during postprocessing.

Fix for bug #28: looks of the borders of a blurred object depend on if the object is the first in the postprocessing bucket.

Postprocessing buffers mBuffer[] are now shared among all postprocessing operations. This saves a lot of memory, but also means that when doing each particular postprocessing, the textures backing up the mBuffer might be too large. We need to fix two things here: when outputting to those too large textures, we need to adjust the Viewport, and when binding those too large textures as input - we need to adjust the TexCoords to compensate....

Improve the 'PostprocessTree' app. Shows bugs in postprocessing.

Simplify postprocessing buffers.

Make the postprocessing buffers static.

A little progress making the postprocessing buffers static.

Introduce possibility that an OutputSurface is backed up by a larger texture than necessary and the 'cloneSize()' method.

Improve Blur (boundaries should be more white than black)
