"Enlarge to fit" button

Currently in Gwenview there are two zoom options in the bottom right.
One is the "100%", which shows the image at its true size.  The other
is "fit", which, by default, will shrink images that are too large but
will not enlarge images that are too small.  There is a configuration
option to change this behavior, "enlarge smaller images, which makes
"fit" enlarge or shrink the image to make it fit the window.  However,
at least personally there are some situations where I want to enlarge
smaller images and some that I don't.  Having to go into the gwenview
settings to change this behavior does not seem to be the most
efficient approach.  I think it would be better if there is three
buttons: "100%", "Fit", and "Enlarge".  100% keeps its current
behavior.  Fit behaves as the current default Fit behavior, that is it
shrinks images but does not enlarge them.  Enlarge will shrink or
enlarge images to make them fit.  Alternatively, you could have
"100%", "Fit" and "Shrink", with "Shrink" behaving like the current
default for Fit and "Fit" now enlarging or shrinking.  Obviously the
gwenview setting would be redundant and would be removed.

If you think this is a good idea I am willing to go ahead and program
it myself if that would help.
