The subset frame options - like the per frame, image, column and row
subset options - 'support' percentage specifications. At best the pct
feature causes confusion; at worst there are bugs, like when trying to
render only the top row of an image.
I "think" all of the bugs are fixed in the yuqk fork, but my proposal
for v4.0 is to dump the percentage specifications. In any case they
should not be layered upon the normal by 'frame number/row/column' flag
and option names.
If later, with v4, we decide the percentage specifications are needed
these should be implemented with their own flag and option sets
(something like: +sf_pct, etc).
