present: Target-msc calculation code cleanup
For better readability this patch improves the code style. No functional changes should be the result. In detail:
- Rename functions and variable to give them more meaning and keep them consistent.
- Unfold and extensively annotate the target-msc adjustment function, to make it easier to understand what's happening and why.
- Hand over scalar values as arguments instead of pointers when possible.
- Change arguments and return values of functions to improve inner and outer semantic of the function.
