Remove variable frameloops

[robalni]

It was hard to understand what it meant and it was only used for
determining whether the loop was in the first frame/iteration.
Therefore I replaced it with variable first_frame which has a clearer
purpose.

Looks good to me, please wait for another approval tho

The purpose of the new variable is indeed clearer. However, I ask myself, can't we just get rid of these ifs completely? Perhaps by moving the stuff outside the ifs before the loop (risking some code duplication, but I could imagine not all calls might be needed in the first frame anyway)?

I think the question should really be what is the actual purpose of frameloops aka first_frame?

Removing the variable with its if-statements altogether results in the exact same behavior; plus, considering the int frames parameter does absolutely nothing, it could very likely be a remnant from old code.

If this can be dropped without regressions, then better take that route.
