Moved to custom example, now raylib only supports simulated VR
rendering.
Oculus code was too device dependant... waiting for OpenXR.

A simple 1st person camera... still requires some work...

Matching the same stereo rendering result given by Oculus PC SDK for
Oculus Rift CV1 is very difficult because hardware has changed a lot and
DK2 distortion shader and parameters don't fit on CV1. Some custom
parameters have been calculated to simulate kind of CV1 stereo
rendering. Further work is required on this point.

Oculus Rift CV1 default values seem not to be available...

Stereo rendering has been moved again to Begin3dMode() and End3dMode(),
it has some limitations but makes more sense...

Still thinking about the best way to manage this...

Now it's easier for the user! Just init Oculus device and get stereo
rendering!

...to align it with standard raylib code. Final goal would be having the
same code work for every platform with no changes...

Under design... looking for the easiest and most comprehensive way for
the user to use VR...

Not functional yet...

Probably more useful...

Examples have been renamed for coherence with raylib modules and test
examples have been merged into examples folder.
