Screenshots

Please complete the following information:

• Minecraft Version: 1.12.2
• Mod Version: 6.3.1

This can be fixed by deleting these lines and recompiling the mod: https://github.com/MrCrayfish/MrCrayfishFurnitureMod/blob/master/src/main/java/com/mrcrayfish/furniture/render/tileentity/PhotoFrameRenderer.java#L157-L165

It seems to be a leftover from the TV rendering code.
