99-calibration.conf-35 for Raspbian 9.8 Stretch

# This is the file "99-calibration.conf-35" that the script "LCD35-show" is supposed to copy onto (i.e. overwrite with) /etc/X11/xorg.conf.d/99-calibration.conf on a Raspberry Pi. Don't use the one in https://github.com/goodtft/LCD-show/tree/master/usr/.

# Use this file for Raspbian 9.8 Stretch. Might not work with older or newer versions of Raspbian!
