Changed _typicalItemWidth/Height for Horiztonal/Vertical Layouts to default to 0 from -1 as it is used as-is in some layout calculations, and -1 would give weird results… the other Layout types default to 0, so not sure why Horizontal/Vertical Layout were different?
Fixed potential division-by-zero paths, along with assumed int truncation which needed to be set explicitly via int() casting in Feathers Horizontal/Vertical/TiledColumes/TiledRows Layout classes.
Tab style conformity
Changed comparisons to > 0 from >= 0 to work with _typicalItemWidth/Height being initialized to 0 instead of -1
