Replying to [comment:18 SimonKing]:
> Do you claim that the new version of M4RI is faster? You do claim a
speed-up for M4RIE, on #12841.
No, M4RI shouldn't have changed (at least the stuff, only bugfixes &
refactoring.
That said, there's a new function for inverting upper triangular matrices
which is much faster than the generic method, but it's not exposed yet. I
need to implement the same for lower triangular matrices, then we can
speed up inversions in general.
Furthermore, M4RI ships its own PNG reader/writer now which is much faster
than what we have in Sage and uses much less memory. Again, it's not used
yet. This patch just gets the new version in.
