Now I wonder if any bots will be unhappy we calling | in static const initializations...
Or would that cost runtime init?  Our tests don't detect any..

ubsan generates these.

Needed to make ubsan work.

Default exit value is 77, which causes autotools to "skip" test.

Some clang versions leave a std::round(float) weak symbol around...

We reverse too many times. Can be optimized. But I doubt many fonts
use reverse lookups, so doesn't matter.

Other than not applying user features, this completes morx table
implementation.

Just speculation. Needs tests to determine which is correct behavior.

When building with the auto tools, the manually mantained

cmake to generate the correct config files for us and install them.

Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

"Unused private member" warning turned error.  ugh.
