Previously when there were 5 or more menu items in a pie menu the acceptable angle to select an item was limited to 45 degrees. This makes sense when all 8 menu items are set, however it unnecessarily restricts the range for menu items that don't have adjacent items. Resolve using a 90 degree angle range then checking of the adjacent buttons exist and are a better match. This also resolves a very small dead-zone between adjacent buttons for both 4 or 8 button pie menus. It was possible for a direction to select neither. Compare the direction enum as a tie breaker. Ref !112311.
