Only a single program was used to safely compress all textures in MTG.
This was done using optipng with the following settings:
```
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.
The resulting compression:
| type | size (Bytes) | % of original texture size |
| --- | --- | --- |
| Original | 247,571 | 100% |
| Compressed | 152,189 | 61.5% |
**Summary: Saves 93.14 KB**
A script has been added: utils/optimize_textures.sh which will perform this compression automatically, assuming optipng is installed.
Alter 'large cactus' schematic to place another force-placed cactus node,
to replace the cactus seedling on growth.
Make schematic 5x7x5 to solve rotation, placement and protection check
issues.
Add a y-slice probability for height variation.
Growth time is tuned to not make this a faster way to obtain cactus nodes
compared to normal cactus farming.
Seedling texture by Extex101.
Use sapling/seedling description in protection intersection message in
'sapling_on_place' function.
