Alpha Raycaster is a custom raycaster for UI texture-based elements built upon default Graphic Raycaster. It checks texture transparency, before deciding whether to send input events for targeted object, which allows a
precise interaction with objects that have a non-rect shapes (like
circles,
triangles,
map regions,
text, etc).
