PMVMatrix rewrite using Matrix4f, providing SyncMatrix4f* for GLUniformData; Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*)

Big Easter Cleanup
- Net -214 lines of code, despite new classes.
- GLUniformData buffer can be synced w/ underlying data via SyncAction/SyncBuffer, e.g. SyncMatrix4f + SyncMatrices4f
- PMVMatrix rewrite using Matrix4f and providing SyncMatrix4f/Matrices4f to sync w/ GLUniformData
- Additional SyncMatrix4f16 + SyncMatrices4f16 covering Matrix4f sync w/ GLUniformData w/o PMVMatrix
- Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*)
- Moved FloatUtil -> Matrix4f, kept a few basic matrix ops for ProjectFloat
- Most, if not all, float[] and int[] should have been moved to proper classes
- int[] -> Recti for viewport rectangle
- Matrix4f and PMVMatrix is covered by math unit tests (as was FloatUtil before) -> save

Passed all unit tests on AMD64 GNU/Linux
