AnimMatrix -- Create a rotation animation matrix

Description

An option to create a rotation animation for the GraphicsObject. The value can be a single 4x4 matrix, or a list which is cycled. The syntax n => ... can be used to repeat a sequence n times (where 0} means infinity). The animation automatically loops (use 0 => { } to stop!) In order for the animation to work, VectorGraphics.css and VectorGraphics.js must be included in the web page.
