Mention what zlib compression level is used in man page / help option + allow user to select compression level
Hello, I'm trying to figure out what zlib compression level is used. I looked a bit at the source code and it looks like GZlibCompressor is included but I just can't figure out what level it is used with or if it is even really used (found no methods being called). I read several files and even looked at GTK documentation. Would be nice if you could answer that here and eventually add that info to the man page and help overview as well.
Also it would be nice if there was a parameter to actually set the compression level.
