fast items

Fast Items flattens dropped items and item frame contents into 2D sprites on the client to cut down draw calls and smooth out FPS in cluttered areas.

What it does:

• Replaces the dropped item renderer with a billboarded GUI-style sprite; optional custom texture overlay (customTextureEnabled) and reduced duplicate copies (combineCopies).
• Replaces item frame contents with the same 2D treatment to keep wall displays lightweight.
• Hotkey toggle (default K) flips between flat sprites and vanilla rendering with actionbar feedback.
• Optional low-FPS safety: auto-enables flat rendering when FPS drops below the configured threshold.

Config details (config/fastitems.json, created on first launch):

• renderDroppedItems / renderItemFrames control which targets use 2D sprites; enabled is the global master switch.
• force2dItems and force3dItems accept exact item ids, namespace prefixes ending in *, or tags prefixed with # to carve out exceptions or whitelists.
• combineCopies keeps each stack to a single sprite; this does not merge separate entities, only trims per-stack duplicates.
• customTextureEnabled with customTexture lets you supply any texture path (defaults to the bundled flat sprite).
• autoEnableOnLowFps and fpsThreshold control the automatic low-FPS trigger; actionbar messages can be muted with showActionbarMessages.

Known notes/limitations:

• Item frames only draw the flattened item; the physical wooden frame is skipped while 2D mode is active.
• Custom textures should point to a valid textures/...png resource from any loaded pack; restart after editing the config to swap textures.
