Only a single program was used to safely compress all textures in MTG.
* `optipng -o7 -zm1-9 -nc -strip all -clobber %%f`
The key command used is -nc, which stops color mode changes. I.e. any RGBA textures will remain RGBA textures, with none being changes to 8-bit indexed mode.
utils/optimize_textures.sh performs this compression automatically, assuming optipng is installed.
Use Calinou's textures from moreores mod.
Craft bronze from tin and copper instead of steel and copper.
Match ore density to the moreores mod but start ore at a depth of
y = -32 to be part of the depth progression of other ores.
