Can be used to change the orientation of a touchscreen.
Example usage with swaymsg:
# identity
swaymsg input type:touch calibration_matrix '"1 0 0 0 1 0"'
# 90 degree clockwise
swaymsg input type:touch calibration_matrix '"0 -1 1 1 0 0"'
# 180 degree clockwise
swaymsg input type:touch calibration_matrix '"-1 0 1 0 -1 1"'
# 270 degree clockwise
swaymsg input type:touch calibration_matrix '"0 1 0 -1 0 1"'
