-- Well, here we have yet another math font that does things differently: a huge prime in the ssty1
-- slot (not an alternate but a single) and a small one in the normal location. Actually, only primes
-- have an ssty feature. Now, because we have some magic with primes in ConTeXt we cannot use some
-- fix-feature or just disable ssty, but we have to revert to a runtime fix. Lucky me that I didn't
-- remove that hardly needed 'tweaks' mechanism yet.
