- Moved IT S70-2 effects alongside the rest of S7x so they all trigger after
paired notes.
- Integrated note on/cut ramping with volume transition ramping to reduce
setup/cleanup overhead of calling render_playing and the resampler functions
for single samples.
- Note on/cut ramping scaled from 7 sample logarithmic and 256 sample linear to
.75ms and 5ms respectively, both linear.
- Integrated the pattern looping changes from DUMB 0.9.3, since a few files
seemed to be broken. The XM-only features still needed to be flagged for XM
so they won't break MOD.
