# `list_geometry` returns the geometry of the focused of visible windows. You can also get they title
# by setting a second argument to `with_description`. The geometry and the title are seperated by `\t`.
#
# Arguments:
#   $1: `focused` or `visible`
#   $2: `with_description` or nothing
#
# Output examples:
#   - with the `with_description` option:
#      12,43 100x200\tTermite
#   - without the `with_description` option:
#      12,43 100x200
