No flags specified,.
Check picking for entities with SpriteRenderComponent. I.e. Text, Annotation, Billboard, Overlay etc.
For multi-pick return - remove entries with same EntityId. Note: May cause slowdown with many hits due to n^2 duplicate removal.
For multi-pick return - remove entries with same EntityId & TextureId. Note: May cause slowdown with many hits due to n^2 duplicate removal.
Return ID if sub-entity picked, not set: return root parent entity.
