That's not very specific.

In any case, I would prefer to see horizontal/vertical speed added as a
property to all the patterns (or rather, all the patterns where it's easy or
useful), rather than add a new pattern.

As a side note, in the near future, I'm planning to convert all the pattern
painting to work on a single AYUV/ARGB scanline, and then have a separate
conversion to the final format.  Among other things, this would make scrolling
patterns a nearly trivial offset adjustment between painting and conversion.
