it means zoom out. For example, $zoom 1 will be 1:1 pixel for

is set manually by @.zoom_level.set and will stay at that level until
changed by code or until zoom mode is changed. This is the
default mode. The Automatic modes will allow the zoomable object
to automatically adjust zoom mode based on properties.
#EFL_UI_ZOOM_MODE_AUTO_FIT) will adjust zoom so the photo
fits EXACTLY inside the scroll frame with no pixels outside this
region. #EFL_UI_ZOOM_MODE_AUTO_FILL will be similar but
ensure no pixels within the frame are left unfilled.
