sloptimizer

optimizes minecraft's startup time and resource reload time by rewriting the solidify filter (in rust :rocket:). fixes the long aah pause near 100% on the loading screen. requires java 25

disclaimer: you probably don't need this mod unless you're playing with 512x512+ textures or have a lot of content mods installed. this mod's mostly a learner project on JNI/FFM, made for myself. it probably doesn't hurt to have, though :)
