Setup and use the RenderTargets.

[fluffyfreak]

These have been in for months without being used!

[fluffyfreak]

The reason for doing this by the way is because it makes a good base for fullscreen effect and is necessary for the Oculus Rift support I've long been developing. I'd rather get it in one piece at a time rather than some huge super-commit.

Instant crash on the legacy renderer :(

What can I do to actually test that this works?

[fluffyfreak]

Legacy, balls.

[fluffyfreak]

I suppose I can add some checks to not use it if we're using the legacy renderer, it's getting quite inconvenient now.
It means no fullscreen effects, rendering the GUI to textures and displaying on things, no 3D instrumentation, no Oculus etc.
OpenGL 2.0 came out in 2004 ... bah

I re-asked the forum if we can kill legacy. Lets see :)

[fluffyfreak]

Updated to master

[fluffyfreak]

Dropping this in favour of backporting the Post-Processing work done for Paragon

[fluffyfreak]

I realised why I ever wanted this committing!
For one thing it's what I built the damned Oculus Rift support atop and I want to extend it eventually for GUI render targets and picture-in-picture cameras.
It's been so long that I'd forgotten.

How do I test this?

[fluffyfreak]

Compile and run, if you can see something then it's worked :)

[robn]

Yeah ok, its works :)

Direct GL calls in Pi.cpp are bad. They'll need to go into the renderer somewhere sane. My brain isn't firing right now (badly need sleep) but I'll try to suggest something soon.

[fluffyfreak]

Ok, i've got a change coming but run out of time to get it working properly. off to be now :)

[fluffyfreak]

Ok, think that's done it... NOW i'm off to bed :)

Merged with few style and sanity fixes.

I'm really unhappy with the complete lack of structure and proper integration here, but I don't have the mental space right now to figure out how it should all fit together. Its contained enough and commented enough to not be an immediate problem.
