pogokeen 222e593437 Change some clocks to support sub-tick precision using a new class, ClockTicks. 
Using that higher precision, interpolate at a higher granularity.
Further, truncate the target interpolation time to vertical blank boundaries to avoid producing temporal artifacts.
Fix issues caused by interpolation calculations being handled differently in multiple places (and fix cases where smoothratios were being thrown away only to be redone without checking all proper conditions).
Ensure ClockTicks changes do not break other targets (EKenBuild, VoidSW), but note any interpolation there is not similarly updated.
