Backports 1.9+'s entity glowing effect to 1.8.9
Inspired by Microcontroller's EntityGlow mod and Biscut's LobbyGlow mod
Compatible with certain multi-version servers (like Hypixel) that send the necessary entity data. While 1.8.9 technically had entity outlines as a Spectator-only feature, this mod makes them available during normal gameplay and backports rendering changes made in 15w51a (1.9) so entity layers and items get properly outlined.
Small disclaimer: This mod does not provide a config screen, so in order to toggle on/off the mod or change settings, you will have to use a mod like OneConfig or manually edit the config file.
