/*
There are 3 "categories" of Battle Frontier transition
1. The full logo is used (B_TRANSITION_FRONTIER_LOGO_*)
2. Small squares with the logo on it are used (B_TRANSITION_FRONTIER_SQUARES_*)
3. The balls that make up the logo come together to form the full logo (B_TRANSITION_FRONTIER_CIRCLES_*)
This file handles category 3. Functions for the other two are handled in battle_transition.c
