Polymer: factor out wall y panning coefficient calculation.

Non-pow2 wall/mask drawing in classic introduced cases where walls are
drawn "incorrectly" because they were constructed with the old behavior
in mind.  Polymer appears to "correct" for it partially, but doesn't cover
all cases.  Specifically, now we have:
 - E1L1 first inside secret room (5000, 50000): Polymer draws like Duke 1.5,
   classic now draws with an offset.
 - E3L2 near the vault (-20000, 25000): both classic and Polymer draw with
   offsets compared to Duke 1.5, but they're different!

This means that more research is needed into what makes these two cases
diverge, even though both have the same root cause.

!!! Also, mappers should abstain from using non-power-of two textures on
    walls until this issue is resolved in a satisfactory fashion !!!

Classic: fix glitches where stuff would be drawn transiently on sect change.

This was introduced with r2771, which fixed e.g. AMC TC city_si's mirrors,
but instructed the base drawrooms inside yax_drawrooms to not correct the
passed sectnum.  Therefore, stuff would get drawn wrongly when passing
sector boundaries, like from the platform to the rails in trueror1.map.
