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! ^_^
