Bug 1394284 - add fallback discrete procedure for transform animation. r=boris,hiro According to the spec, if one of the matrices for transform interpolation is non-invertible, the used animation function must fall-back to a discrete animation. However, in the current implementation, we always use an identity matrix as a fallback for the non-invertible matrix. Decompose2DMatrix and Decompose3DMatrix both return a boolean, but we just never use it. So, in this patch, we use the returned boolean from the matrix decomposition as a condition, and do the fallback discrete procedure for the non-invertible matrices case.
