Is there a textured but unlit (full bright) viewport mode? I'm trying to display models that have shading drawn or baked directly on the textures, but I can't figure out how to disable Blender's default scene lighting. If there are no lights in the scene, everything is black, but I want to see the textured objects fully bright. How do I disable the lighting?

NOTE: Just before posting this, I found the "Shadeless" material property, which does more or less what I want. However, is there a way to globally toggle the default lighting?
Yes, you can enable Shadeless in 3D view > Properties (N) > Shading while in textured view:



If you are in BI, this only works if using Multitexture shading:



If you are using GLSL in BI or material shading in Cycles, you'll have to use shadeless in the material settings for BI and a emission shader for cycles.
