Add connected textures and other graphical tweaks

Vanilla Minecraft would benefit greatly from features offered in some mods (optifine) and shaders. This would include: —Connected glass panes (which look infinitely better than the vanilla look) —Carrying a torch can light up the surrounding areas instead of needing to place it —Grass/snow blocks having texture on the side and not just the top —Grass and plants sway in the wind as they do in shaders. Forgive my ignorance on technical matters but I feel like this wouldn’t impact performance all that much and would greatly improve gameplay.
