Short description of error
bpy.types.MaterialTextureSlot <== what is this?

Exact steps for others to reproduce the error

1. Buttons Context
2. bpy.context.texture_slot
3. bpy.types.MaterialTextureSlot <== this links to nowhere

should this be pointing to bpy.types.MaterialSlot ?

or possibly to bpy.types.Material.texture_paint_slots ?

thanks for blender!!
