Retroquad 0.18.4 Released (Patreon)

The new cvar to control edge caching is r_edgecache, which is enabled by default since we've found out that the buggy edges were caused by faulty BSP compilers.

However, in my tests I barely saw any performance improvement with edge caching enabled. The difference was a small fraction of a frame per second, no matter how complex the scene was. So, it's very likely that I'll remove the edge caching code entirely later on, to simplify the renderer a bit.
