) 
 

Extracts out the components of an affine matrix.

Returns true if the scale, hpr, translate completely describe the matrix, or false if there is also a shear component or if the matrix is not affine.

This flavor of the function accepts an expected roll amount. This amount will be used as the roll component, rather than attempting to determine roll by examining the matrix; this helps alleviate roll instability due to roundoff errors or gimbal lock.
