GetCompensatedQFPtrFilterUnit()

FilterUnitQFPtr GetCompensatedQFPtrFilterUnit	(	FilterType	type,
		FilterSubType	subtype
	)

Returns a filter unit pointer and optionally applies gain scaling.

The gain scaling attempts to make levels at cutoff extream (so open for LP closed for HP) the same as bypassing the filter when sent a full spectrum saw wave. Roughly. But really it's just some constants we bodge in to turn up vintage and turn down saturated ones.
