-    * It was first built to efficiently maintain the WebGlBuffer that contain instancing based data.
-    * Allocating an Element will return a instance of DynamicFloatArrayElement which contains the offset into the Float32Array of where the element starts, you are then responsible to copy your data using this offset.
-    * Beware, calling pack() may change the offset of some Entries because this method will defragment the Float32Array to replace empty elements by moving allocated ones at their location.
-     * This method will return an ArrayBufferView on the existing Float32Array that describes the used elements. Use this View to update the WebGLBuffer and NOT the "buffer" field of the class. The pack() method won't shrink/reallocate the buffer to keep it GC friendly, all the empty space will be put at the end of the buffer, the method just ensure there are no "free holes".

-    * It was first built to efficiently maintain the WebGlBuffer that contain instancing based data.
-    * Allocating an Element will return a instance of DynamicFloatArrayElement which contains the offset into the Float32Array of where the element starts, you are then responsible to copy your data using this offset.
-    * Beware, calling pack() may change the offset of some Entries because this method will defragment the Float32Array to replace empty elements by moving allocated ones at their location.
-     * This method will return an ArrayBufferView on the existing Float32Array that describes the used elements. Use this View to update the WebGLBuffer and NOT the "buffer" field of the class. The pack() method won't shrink/reallocate the buffer to keep it GC friendly, all the empty space will be put at the end of the buffer, the method just ensure there are no "free holes".
