I normally rename these functions with an "_C" after the name, so we'd have "D_DrawSpans16_C". Makes it clear which version you're using. ;)

F. A. Špork, an enlightened nobleman and a great patron of art, had a stately Baroque spa complex built on the banks of the River Labe.

I've tested the mk+mh spans with a release build on Pentium II, and they're actually slower than the Qbism/mh span16 up here. I keep getting 40.2/40.6 with the mk/mh version with timedemo demo1 compared to the qbism version which had 41.2.

Can't say if the optimizations are beneficial for the dreamcast, since that's an overrated piece of hitachi-powered crap
