Texture Sizing Feature

Provide a feature (probably in the textures tab of the Edit window) that will allow you to size a texture to a mall/landlord/server friendly size. With texture rendering being such the problem it has become in the past few months, it would be great if anyone could press a "button" that would size a texture to a reasonable (256X256) resolution. This would cut the load on texture rendering, particularly around malls, tremendously. It would also make it easier for Landlords to ask for texture size limits from the tennents and expect to get compliance.
