Bug 1021: Add OculusVR distortion renderer (single FBO and dual FBO); Add GLEventListener2 (WIP); Refine FloatUtil

- GLEventListener2 extends GLEventListener adds refined control:
  - display w/ flags, i.e. repeat, don't clear
  - setProjectionModelview(..)

- FloatUtil.* Add return value for chaining, where missing

+++

- jogamp.opengl.oculusvr.OVRDistortion
  - Handles all OVR related data and maps it to shader + GL buffers
  - display method

- com.jogamp.opengl.oculusvr.OVRSBSRendererSingleFBO implements GLEventListener
  - Simple OVRDistortion renderer using single FBO
  - Using upstream GLEventListener2 (the content)

- com.jogamp.opengl.oculusvr.OVRSBSRendererDualFBO implements GLEventListener
  - Simple OVRDistortion renderer using two FBOs
  - Using upstream GLEventListener2 (the content)
