(XMB/Ozone Monochrome) Update 'export' scripts to ensure white transparent pixels + regenerate assets
Created by: jdgleaver
This is a follow-up to PRs #347 and #348.
It modifies the export.sh
and export_ozone.sh
scripts of the XMB Monochrome theme to ensure that all generated PNG files have white transparent pixels.
These scripts have then been run to update all affected assets.
