Extracts out the components of a 3x3 rotation matrix. Returns true if the scale and hpr 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.

Extracts the rotation about the x, y, and z axes from the given hpr & scale matrix, given the indicated roll amount as a hint. Adjusts the matrix to eliminate the rotation. This function assumes the matrix is stored in a right-handed Y-up coordinate system. Definition at line 228 of file compose_matrix_src.cxx. References FLOATTYPE, x, and y.
