Describe the bug

Beacons rendered by Distant Horizons will have weird cyan and magenta colors when they should just be white.

Describe how to reproduce the bug

Look at a beacon that is outside of the default Minecraft render distance.

distant horizons added new shader programs which i have not yet added. this is simply the result of no special handling.
it will be fixed in the next commit

i have added these programs in the unstable-development branch, if you want to try it

it should be coming to the main branch soon-ish
