In the current implementation, if there is any interpolation error in a matched transform function pair, we fall-back to use InterpolateMatrix unconditionally. However, the error could be caused by: 1. mismatched transform function pair 2. matched transform function pair within at least one undecomposable matrix. Using InterpolateMatrix for case 1 makes sense, however, using InterpolateMatrix for case 2 does not. According to the spec, we should just report error for case 2, and let the caller do the fallback procedure. Using InterpolateMatrix for case 2 will go through more unnecessary code path, and produce more memory usage and calculation cost, which should be avoidable. In this patch, we add an extra pass to check if a transform function pair have matched operations in advance. With this information, we can easily tell whether the interpolation error in a equal-length transform function pair is caused by case 1 or case 2. So, we can avoid the unnecessary cost.
