Added hacky script to quickly cut apart dual-screen wallpapers. I run two 1920x1080 screens side-by-side, so I just cut double wide wallpapers in two and display one on each screen. Script is very inflexible on probably not too useful for the future but it works for its purposes now.

# A simple script to make it easy for me to crop newly found wallpapers
|
|
# to size, for one 1920x1080 screen on the left and one on the right.
|
|
# The resulting images can be used with wallpaper programs (e.g. swww)
|
|
# to nicely display per monitor without stretching.

#
|
|
# Usage: wallcrop.sh path/to/my/imagefile.jpg
|
|
# It will drop two cut versions in the same directory and tell you where
|
|
# they are.
|
|

|
# TODO check image dimensions and warn user if not 3840x1080, or at least if smaller than cropped area
