natural stone - is for sloping, but not falling, so?
granular materials - must slope, fall and spread by default
and new category: gravity blocks - must be not sloping, falling, and not spreading, or spreading after column height reach setted value.
by example - cobblestone - is not natural, not completely granular, and also not solid, and it should be affected by grafity, stackable up, but fall off from column higher than 2. (eg).
