[TYPO3-core] FYI24: Fix issue #10713: Refactor tslib_gifBuilder::calcOffset()

[Oliver Hader]

This is an announcement of a SVN change that will be committed in 24 hours.

Type: Feature/Cleanup

Bugtracker references:
http://bugs.typo3.org/view.php?id=10713

Branch: Trunk

Problem:
The method tslib_gifBuilder::calcOffset() takes strings like
"123,10.h+13+20.h" and calculates the values. However, it can be handy
to have this calculation available for each single segment of that list.

Solution:
Refactor tslib_gifBuilder::calcOffset() to be able to reuse calculation
functions on single segments like "10.h+13+20.h" and move that
functionality to a new method called calculateValue().

Notes:
I removed the intval() calls at the modulo and division operations since
the given value is already an integer. This cleanup is part of RFC #10666.
