graphene:matrix-interpolate (a b factor result)

a -- a graphene:matrix-t instance
b -- a graphene:vec3-t instance
factor -- a number for the linear interpolation factor
result -- a graphene:matrix-t instance

The graphene:matrix-t instance with the interpolated matrix.

Linearly interpolates the two given matrices by interpolating the decomposed transformations separately. If either matrix cannot be reduced to their transformations then the interpolation cannot be performed, and this function will return an identity matrix. The factor argument ist coerced to a double float before being passed to the foreign C function.
