Revert last changes to the postprocessing FBO.
This reverts commit 2dbed690bdbee80d9bfb22c800073855eb5d0946.
In an attempt to contain the flashes on Mali GPU, re-structure the post-processing FBOs from 1 FBO with 2 color attachments + combined depth-stencil to 2 separate FBOs sharing a depth-stencil texture.
Result: this appears to make the flashes slightly worse.
Internal API change around postprocessing.
Fix quality levels in Glow.
Progress with Glow.
Simplify Statics.
Introduce concepts of 'in' and 'out' postprocessing qualities.
Make Postprocessing quality per-effect (rather than applied to the whole queue)
Javadoc.
Now all PostprocessEffects are truly self-contained, including dynamic enable() and all shader sources.
All knowledge about Postporcessing moved to the respective Effect classes.
Simplify Effect classes.
Progress with Effect classes - everything compiles now!
Progress with support for Effect classes.
The library compiles now!
Some progress with Effect classes.
Big mess - nothing compiles now; classes moved around.
Beginnings of support for Effect classes.
