Switch DraStic from Bilinear to Nearest Neigbour

By default DraStic is using Bilinear filtering which can appear blurry. To switch this mode to Nearest Neighbour and back you can use this script.

This can be run from the muOS Backup Manager. Simply put it in your /mnt/mmc/MUOS/backup folder and launch it.

DraStic Switcher.sh
#!/bin/sh
 
# Scaling adjustment script created for muOS 2405 Beans +
# Lets you switch between Nearest Neighbour (sharper) and Bilinear (smoother)
 
# Fire up the logger!
