[Feature request] Allow "Fill Window" as an option in the "Initial zoom ratio"
Hi. Currently there are only 2 options in "Initial zoom ratio": 1:1 & "show entire image" There are many users need to use "Fill Window" as a default initial zoom ratio & it is not conventional to set this value every time open new image & will be more convenient to have "Fill Window" as a 3rd default initial zoom ratio.
