It won't be every frame, but I think there are various things besides 
editing the texture that can cause textures to be reloaded.  For 
instance resizing the view or moving the window to a different 
monitor.

Yes, I think so.  IRRenderer_Texture_Set only calls 
ir_texture_cache_add for textures that are not already known to 
OpenGL.
