Bug 1490 - GraphUI Group: Resolve Performance Issues with Shape Mv Transform -> PMVMatrix4f

Shape.setTransformMv() is called for each renderer frame and for each shape,
involving 6 Matrix4f.mul() and set*() operations.

Since mutation of shape's position, rotation or scale is less frequent
than rendering one frame (for all shapes),
it is more efficient to maintain a local Matrix4f and update it
on such single mutations.

Rendering then only needs to perform one Matrix4f.mul() operation
using this internal matrix.

Also changes name from setTransformMv(PMVMatrix4f) to applyMatToMv(PMVMatrix4f),
as its name might be misleading.
