It didn't make sense to me for Esetroot -scale -mirror to produce
exactly the same image as Esetroot -scale. The attached patch (for
yesterday's CVS) makes that combination produce a horizontally-flipped
version of the image produced with -scale.
I also added a -Flip argument for vertical flipping, which can be used
either with -mirror or independently.
The only troubles I see are that the -F flag, by itself, does nothing,
and that there is no indication in the usage text as to the dual
functionality of the -mirror flag. If anyone sees other problems, or
easy ways to handle these, please do let me know.
Apologies if this isn't in proper form; this is the first time I've ever
modified C code I hadn't written myself, and what do you know, it works! ^_^
