Charles, You do want to have everything on as few textures as possible to minimize draw calls. From what I gather from reading on the OpenGL forums, at some point there is a tipping point where it doesn't make sense to go bigger. If you create a texture of 16384x16384xRGBA, it will consume 1GB of system/video RAM (if my math is right). Having a default to a more reasonable size is probably better, even if it costs a few draw calls. People who actually need textures that big can simply create their own TextureAtlas manually, as advanced users probably already do.
Magu, (Sorry, your name shows up as "magu...." so I'm not sure what your actual name is!), I feel that the resources module should at least have sane defaults for people who don't know what a TextureAtlas is. If you're already making your own atlases, you don't really need to use the resource module unless to fetch image data, and add it to your own Atlas.
