* Allow setting texture data from 1x to fix some textures resetting randomly Expected targets: - Deltarune 1+2 - Crash Team Racing - Those new pokemon games idk * Allow scaling of MSAA textures, propagate scale on copy. * Fix Rebase Oops * Automatic disable * A bit more aggressive * Without the debug log * Actually decrement the score when writing.
