The 4x4 matrix type has a larger alignment requirement of 16 bytes
than the default, but it was stored in a generic vector of bytes. There
are a few solutions that reduce the memory reuse in this code path--
the chosen solution uses a custom allocator which always allocates
with an alignment that should be large enough for anything.
