Increase Texture Size Limit for Items and Bitmaps on Servers

The current 512x512 texture limit for items, bitmaps, and custom assets restricts server customization. Increasing this cap would enable servers to use higher-quality textures for custom items, models, and GUIs, enhancing the visual experience. Mods already bypass this limit, but native support would improve compatibility and unlock more creative possibilities.

Larger textures would also future-proof the game for better performance on modern systems, allowing more detailed, polished visuals for advanced servers.
