tan(fovy), fix callers; Simplify FloatUtil.makePerspective(..FovHVHalves..)
Fix FloatUtil.makePerspective(..): The tan(fovy/2) shall be used, not tan(fovy), fix callers
- This bug didn't hit (yet), since callers already performed the division (degree -> radian)
by falsly claiming the passed value is in radian - where it was actually fov/2 in radians.
Simplify FloatUtil.makePerspective(..FovHVHalves..)
- Due to the fix above, it became pretty clear that the makeFrustum(..)
method can be utilized.
Simply apply all our tan-half-fov values on zNear.

'com.jogamp.opengl.util.stereo' contains all public interfaces/classes
Renamed interfaces:
CustomRendererListener -> CustomGLEventListener
StereoRendererListener -> StereoGLEventListener
New vendor agnostic 'stuff' in com.jogamp.opengl.util.stereo:
1 - StereoDeviceFactory
To create a vendor specific StereoDeviceFactory instance,
which creates the StereoDevice.
2 - StereoDevice
For vendor specific implementation.
Can create StereoDeviceRenderer.
3 - StereoDeviceRenderer
For vendor specific implementation.
4 - StereoClientRenderer
Vendor agnostic client StereoGLEventListener renderer,
using a StereoDeviceRenderer.
Now supports multiple StereoGLEventListener, via add/remove.
- MovieSBSStereo demo-able via StereoDemo01
can show SBS 3D movies.

adjust FBO texture params (alpha, filtering); Demo: Pass all parameters w/ arguments, use sane good defaults.
Turns out that using bilinear texture filtering w/o multisampling is 'good enough' ..
- OVRSBSRenderer*:
- Add texture filtering parameter (bilinear/none)
- Adjust FBO texture params (alpha, filtering)
No alpha needed in FBO sink/target!
- Demo: Pass all parameters w/ arguments, use sane good defaults.

Refine API in regards to proper package names, interface
and high-level access to eye specific constant parameter
and variable eye movement.

Commit 36327e24cf586b50bf18e87d7d13d53eb41cf1d9 introduced 'GLEventListener2'
Move javax.media.opengl.GLEventListener2
-> com.jogamp.opengl.util.CustomRendererListener
-> com.jogamp.opengl.util.stereo.StereoRendererListener
StereoRendererListener adds stereoscopic specific:
public void reshapeEye(final GLAutoDrawable drawable, final int x, final int y, final int width, final int height,
final EyeParameter eyeParam, final EyePose eyePose);
.. see below.
++
Add com.jogamp.opengl.util.stereo:
- EyeParameter (Constant eye parameters, like IPD and FOV)
- EyePose (Current eye position and orientation)
+++
Add com.jogamp.opengl.math.FovHVHalves to support
non-centered bi-directional FOV for lenses.
Add respective FloatUtil.makePerspective(.. FovHVHalves fovhv ) variant.

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

Bring-up test only initializes the ovrHmdHandle
data structure by OVR native code.
See com.jogamp.oculusvr.OVRVersion
Current evaluation build compiles all OVR-SDK source
files itself w/o using provided libovr.a.
We also skip the GL dependent renderer of the SDK,
i.e. we prefer to utilize our JOGL 'barrel distortion' renderer.
This eases the 'chicken-egg' problem of OVR SDK dependencies,
i.e. libGL, libGLESv2 .. etc
Since the OVR source code is C++, we may still have to figure out
how to / and whether we shall link libstdc++ statically
to remove platform dependencies.
Right now we link libstdc++ statically if using GCC,
see make/build-oculusvr.xml (hackish .. TODO: better way to include all symbols).
Same consideration applies to GNU/Linux and libudev.so dependency,
since there are:
- libudev.so.0 and (Older distri's)
- libudev.so.1 (Debian8, ..)
...
Produced JAR artifacts are
- jar/atomic/oculusvr.jar
- jar/atomic/oculusvr-natives-<os.and.arch>.jar
i.e. only in 'atomic' variants to not bloat the default 'all' JAR files.
....
make/build-oculusvr.xml Notes:
- Currently native build only enabled on GNU/Linux (isLinux)
- Force disable native build via property 'c.build.oculusvr.skip'
