Additionally to fix the options button, I could either cache the
interface in PlaylistsSongSelectV2 or make the interface cache itself. I
went with the latter option.
This reverts to the way stable does things. Smooth seeking is nice and
all, but slows things down and doesn't give the instant reponse that
mappers are used to.
This should fix some performance issues regarding seeking as it no
longer tries to render large portions of the map during the seek
operation.
Note that I've also forced the summary timeline to always non-smooth
seek. It was bugging out in weird ways when doing smooth seeks and I
don't want to attempt to fix it.
I found this way too high in the editor, not giving enough feedback when
seeking.
To recap, this was put in place to avoid glitchy sounding audio. Such
glitchiness only occurs with *very* fast seeks. This is still well
within sane range.
