Ray, AABBox, Frustum, Stereo*, ... adding hook to PMVMatrix
Motivation was to simplify matrix + vector math usage, ease review and avoid usage bugs.
Matrix4f implementation uses dedicated float fields instead of an array.
Performance didn't increase much,
as JVM >= 11(?) has some optimizations to drop the array bounds check.
AMD64 + OpenJDK17
- Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest)
- Matrix4f.mul(b) roughly ~3% slower than FloatUtil.multMatrix(a, b, dest)
- FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all
- Matrix4f.invert(..) roughly ~3% slower than FloatUtil.invertMatrix(..)
RaspberryPi 4b aarch64 + OpenJDK17
- Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest)
- Matrix4f.mul(b) roughly ~20% slower than FloatUtil.multMatrix(a, b)
- FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all
- Matrix4f.invert(..) roughly ~4% slower than FloatUtil.invertMatrix(..)
Conclusion
- Matrix4f.mul(b) needs to be revised (esp for aarch64)
- Matrix4f.invert(..) should also not be slower ..

if zNear == zFar
throws GLException with GL_INVALID_VALUE if zNear is <= 0, or zFar < 0,
or if left == right, or bottom == top, or zNear == zFar
Add note on callers:
- FloatUtil.makePerspective(..)
- Matrix4.*
- PMVMatrix.*
- ProjectFloat.*

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)
