Math and PMVMatrix: Cleanup and Refine

- Added final qualifier where possible

- Refined API doc

- FloatUtil:
  - Add machine EPSILON
    - fixed value and runtime computed (real machEps)
    - incl. isZero(..), isEqual(..)

  - Add makeRotationAxis(..)
    - Moved from PMVMatrix for reusage

  - Add makeRotationEuler(..)
    - New, not recommended due to Gimbal-Lock

  - Add copyMatrix[Column|Row](..)

  - Add more PI variations and trigo-func float mappings

  - Removed cross and normalize, use VectorUtil!

VectorUtil:
  - Add copyVec*
  - Add equals and isZero w/ and w/o EPSILON
  - Add distance[Square]
  - Add length[Square]

PMVMatrix:
  - Removed 'destroy' method in favor of making most fields 'final'.

AffineTransform:
  - Added AABBox transform
  - Public multiply
