Non-linear effects now process tracks before mixing.
This will be slower when multiple tracks are selected
but the preview should now match the applied effect.
SetLinearEffectFlag(true) allows linear effects to
preview more quickly when multiple tracks selected, by
pre-mixing selected tracks.
Simple generators like Tone and Noise may be marked as
'linear' so that they only preview a few seconds.
Generators that vary over time (such as Chirp) must use
the full duration that is set. As this currently
requires calculating the full duration, preview for
'non-linear' generators are not limited to the preview
length.
