* Fix FSAA in UI and lower VRAM consumption (#313)

* Fix FSAA in UI and lower VRAM consumption

FSAA was being requested however due to how the compositor was setup,
this effect was not taking effect.

Additionally, the Compositor setup was improved to lower memory
consumption. Originally the setup was taken from Ogre samples which
assume they will ultimately be rendering to a window.

However this is not the case and thus IGN was creating 3 render targets
(two for ping-ponging between postprocess FXs + one for storing the
final result)
This was optimized so that we only create 2 render targets: two for
ping-ponging between postprocess FXs and we pick at runtime which one is
storing the final result via the new variable renderTargetResultsIdx

Further performance optimizations could be made in Ogre 2.2 to improve
unnecessary MSAA resolving when doing postprocess, though considering
there's currently only one postprocessing effect (the Gaussian filter) I
doubt this optimization would make much of a difference

* Undo VRAM saving optimization: It cannot be applied

The "Final Composition" node requires both textures to be resident.
Thus 2nd texture must always be resident.

The optimization could still be applied if we create two Final
Composition nodes (one for when 2 textures are needed, another for when
only MSAA + 1 texture is needed) but this would:

  1. Hurt code readability too much (i.e. what is going on?)
  2. Increase debuggability difficulty too much because codepaths taken
would differ depending on whether optimization was applied. Also certain
bugs could remain hidden until compositors are toggled.

This was causing ogre2_demo to fail.
