Improve Texture Atlas

[memelotsqui]

Current texture atlas generation creates same section size for each texture as image

But some of them are more important than other (for example, body section should be bigger than small details like litlle plant in the head)

We should make the atlas creation consider texture sizes and trait importance to determine it's size in the atlas

Is there any blockers to this or could someone just add a texture packer that takes into account the original texture size?
