BTW, I'm not sure what's the best solution but you can calculate the 
slide without iterating all images. Look at the first statements in 
"tlv_allocate_and_initialize_for_key" in [1]. Specifically where it sets 
the "slide" variable.

I think it would be simpler to only have one way to do this.

Fair enough.

I agree, but I think ctor/dtors can be used for the executable as well.
