This commit performs both lossless and lossy compression on every .obj and .png in homedecor. The .png files were all 100% losslessly compressed using ect.exe and optipng.exe (more details below) at maximum settings. The .obj files were lossy-compressed so that comments were removed, trailing 000's were removed and all numbers rounded to 3 decimal places max. Blender exports at 6 decimal places but for minetest, 3 decimal places is the absolute maximum a person with anything under a 256K screen will ever need.
## Results
```
Original entire modpack size: 6343.5 KB
New entire modpack size: 5312.2 KB
Total Reduction: 1031.3 KB (16.3% less)
```
Please note that actual media size is likely more like 4,500 KB so media reduction is more around 20-25%.
## Details / What actions were actually performed
Used these programs:
https://github.com/ExeVirus/Compress-Objhttps://sourceforge.net/projects/optipng/https://github.com/fhanau/Efficient-Compression-Tool
Ran this command on every .obj: (fast)
```
luajit.exe compress.lua -f <file> -precision 3
```
Ran these commands on every .png: (slow)
```
ect.exe -9 -strip --allfilters-b <file>
optipng.exe -o7 -strip all -clobber <file>
```
Note that for future compression, I recommend only using optipng.exe instead of both. ECT can get better results but it takes a LOT longer and only ever saves another 1-2% of the file size. Not worth an extra 10-20 seconds per texture file in my opinion.
## Time spent
Roughly 2 Hours from start to finish + commit + PR
by extension, require its presence to cause doors to be 3d
for consistency with the appearance/style of mtg doors in worlds that
wouldn't normally use the 3d extras mod
minor rework of closet door textures to make them work decently in both modes
Any of these new submods can be run without any other
components that were once part of the big "homedecor"
mod, other than homedecor_common and homedecor_i18n
Reduced dependencies where possible, but each submod still
has its various dependencies more or less the same as before,
i.e. some need basic_materials, others need unifieddyes,
some need building_blocks, and so on.
All of the stuff that used to be under homedecor/handlers
got moved to homedecor_common, as did any models and/or textures
that are used by more than one other homedecor component.
All the miscellaneous items that didn't warrant their own
mod ended up in homedecor_misc, which can also be thought
of as the remains of the original "homedecor" mod, renamed.
more efficient use of texture space, fewer polys, less wasted vertices.
also made it and empty bookshelf use default wood where possible, and
composite the inside-back texture from overlay + default wood.
since forever.
Also clarify it in the copyright message, spread the license file around
a bit, and remove some useless "last changed" dates since they've been
inaccurate for a long time.
