- *
+ * This duplicates the Blender manipulate tool.
+ * It supports quick access to Grab, Rotate, and Scale operations

+ * Those keys can be followed by an axis key to specify what axis
+ * to perform the transformation: x, y, z

+ * BUGS:

+ * 2) ESC will not reset currentState (ESC get hijacked)
+ * 3) rotation towards screen is busted (wrong axis)
