create implication ass_visible_through_thighs -> thighs
The thighs must be visible to use the ass_visible_through_thighs tag.
I don't know if there are any specific conditions to use the thighs tag, the wiki page doesn't make it clear; if there are thighs in the image, we can use it, right? please, correct me if I'm wrong.
EDIT: The tag implication ass_visible_through_thighs -> thighs (forum #147993) has been rejected by @Hillside_Moose.
