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.

[07-27 10:02] <jp__> Hi Vanessa. I replaced the LazyJ's smokes nodes by few particules : https://forum.minetest.net/viewtopic.php?p=149534#p149534
[07-27 10:03] <jp__> Now I think this mod is mature for integrate Homedecor...
[07-27 10:17] <VanessaE> LazyJ: homedecor is LGPL. your code is GPL. by extension so is jp's fork.
[07-27 10:18] <VanessaE> I'd like to include his fork of your mod into homedecor modpack.
[07-27 10:18] <VanessaE> your permission is required :)
[07-27 10:18] <LazyJ> Ok.
[07-27 10:18] <LazyJ> What's the difference between LGPL and GPL? I just go with whatever the original author uses.
[07-27 10:19] <VanessaE> beats the hell out of me exactly except LGPL is supposed to make it easier to use code so-licensed in proprietary projects or something.
[07-27 10:19] <VanessaE> I only use it because minetest_game did and I got some code from there.
[07-27 10:20] <LazyJ> Ok with me to use it.
[07-27 10:21] <LazyJ> Credit to semmett9 too.
