Well, Talon's original suggestion was implicitely wanting a png format, so I believe the current drawsave -v won't work for him.
I'm not sure how one can use the binvar atm if not to /bwrite it, which drawsave already offers.
I believe that we need to be able to indicate the format for binvar as well, I'm not even sure the current format is something people want. I think saving to a binvar should offer the same format as saving to a file.
One issue is that the png format was based on the file extention and with binvar, there's no way to find out. A new /drawsave -p switch could be added, to specify the png format (could then allow a filename without extention when saving to disk as well) in this case.
