The current "Scale" mode crops out part of the image if the scaled image is larger than the terminal in any direction. This is useful for most cases, such as wallpapers repurposed as terminal backgrounds. However, this may be surprising to users coming from xfce4-terminal, where the equivalent "Scaled" mode tries to fit the background within the terminal in both dimensions. This new "Scale (fit)" mode is meant to emulate this behaviour.
I'm aware that Tilix is currently in low-maintenance mode and looking for a new maintainer, but since this mostly builds off of the "Scale" background image mode, I feel that this addition is fairly minor. Feel free to close this PR if it would carry too much of a maintenance burden.
Here are some examples of the differences between "Scale" and "Scale (fit)" using a typical background and a background well suited to "Scale (fit)":
Typical background, Scale
Typical background, Scale (fit)
Transparent PNG, Scale
