/**
* PMVMatrix4f implements the basic computer graphics {@link Matrix4f} pack using
* projection (P), modelview (Mv) and texture (T) {@link Matrix4f} operations.
* <p>
* Unlike {@link com.jogamp.opengl.util.PMVMatrix PMVMatrix}, this class doesn't implement
* {@link com.jogamp.opengl.fixedfunc.GLMatrixFunc GLMatrixFunc} and is OpenGL agnostic.
* </p>
* <p>
* This is the second implementation of `PMVMatrix4f` using
* direct {@link Matrix4f}, {@link Vec4f} and {@link Vec3f} math operations instead of `float[]`
* via {@link com.jogamp.math.FloatUtil FloatUtil}.
* </p>
* <p>
* PMVMatrix4f provides the {@link #getMvi() inverse modelview matrix (Mvi)} and
* {@link #getMvit() inverse transposed modelview matrix (Mvit)}.
* {@link Frustum} is also provided by {@link #getFrustum()}.
*
* To keep these derived values synchronized after mutable Mv operations like {@link #rotateMv(Quaternion)}
* users have to call {@link #update()} before using Mvi and Mvit.
* </p>
* <p>
* All matrices are provided in column-major order,
* as specified in the OpenGL fixed function pipeline, i.e. compatibility profile.
* See {@link Matrix4f}.
* </p>
* <p>
* PMVMatrix4f can supplement {@link com.jogamp.opengl.GL2ES2 GL2ES2} applications w/ the
* lack of the described matrix functionality.
* </p>
* <a name="storageDetails"><h5>Matrix storage details</h5></a>
* <p>
* The {@link SyncBuffer} abstraction is provided, e.g. {@link #getSyncPMvMvi()},
* to synchronize the respective {@link Matrix4f matrices} with the `float[]` backing store.
* The latter is represents the data to {@link com.jogamp.opengl.GLUniformData} via its {@link FloatBuffer}s, see {@link SyncBuffer#getBuffer()},
* and is pushed to the GPU eventually.
* </p>
* <p>
* {@link SyncBuffer}'s {@link SyncAction} is called by {@link com.jogamp.opengl.GLUniformData#getBuffer()},
* i.e. before the data is pushed to the GPU.
* </p>
* <p>
* The provided {@link SyncAction} ensures that the {@link Matrix4f matrices data}
* gets copied into the `float[]` backing store.
* </p>
* <p>
* PMVMatrix4f provides two specializations of {@link SyncBuffer}, {@link SyncMatrix4f} for single {@link Matrix4f} mappings
* and {@link SyncMatrices4f} for multiple {@link Matrix4f} mappings.
* </p>
* <p>
* They can be feed directly to instantiate a {@link com.jogamp.opengl.GLUniformData} object via e.g. {@link com.jogamp.opengl.GLUniformData#GLUniformData(String, int, int, SyncBuffer)}.
* </p>
* <p>
* All {@link Matrix4f matrix} {@link SyncBuffer}'s backing store are backed up by a common primitive float-array for performance considerations
* and are a {@link Buffers#slice2Float(float[], int, int) sliced} representation of it.
* </p>
* <p>
* <b>{@link Matrix4f} {@link SyncBuffer}'s Backing-Store Notes:</b>
* <ul>
* <li>The {@link Matrix4f matrix} {@link SyncBuffer}'s backing store is a {@link Buffers#slice2Float(float[], int, int) sliced part } of a host matrix and it's start position has been {@link FloatBuffer#mark() marked}.</li>
* <li>Use {@link FloatBuffer#reset() reset()} to rewind it to it's start position after relative operations, like {@link FloatBuffer#get() get()}.</li>
* <li>If using absolute operations like {@link FloatBuffer#get(int) get(int)}, use it's {@link FloatBuffer#reset() reset} {@link FloatBuffer#position() position} as it's offset.</li>
* </ul>
* </p>
