com.bramosystems.oss.player.core.client.geom.TransformationMatrix
Represents a transformation matrix that determines how to map points from one coordinate space to another. The matrix can be used to perform various two-dimensional graphical transformations including translation (x and y repositioning), rotation, scaling, and skewing.
A transformation matrix object is a 3x3 matrix with the following contents:
```
 [ a   b   u ] [ c   d   v ] [ tx  ty  w ] 
```
Note: Property values u and v are always 0.0, while w is always 1.0.
Note:The 3x3 matrix is implemented with a Matrix2D object. @since 1.1 @author Sikirulai Braheem @see Matrix2D
