Downstream packages that subclass position scales need updating

[paleolimbot]

Only two packages subclassing a position scale were identified in the revdeps because they failed for other reasons...position scale subclasses won't error but will instead hide the subclassed position scale (as previously the only correct guide value was "none" for a position scale). These packages need to update guide property on position scale subclasses to waiver(), or axes will stop being displayed after #3356. This will have to be version dependent, as older code does not ignore position aesthetics when building guides. This is the case with dint and ggforce (here and here).

Transformations in position scales must handle NA values after #3398 (which allows NA values in coordinate system limits), which is a problem for one package (dint).

@paleolimbot Have issues been filed with the afflicted packages? I ran into the dint issue the other day.

[paleolimbot]

Done! See s-fleck/dint#3 and thomasp85/ggforce#188 .

[paleolimbot]

Are you aware of any other packages that might be affected? I checked bench, but it doesn't call continuous_scale() directly and its transforms handle NAs.

[clauswilke]

I'm not. I ran into the dint issue by accident, when I needed a date scale in quarters.
