commit 7d6269ecc9945bff9dc00f5eeb62e47e2cf284bb

Removed static context from DisplayPortCalculator
Refactored many fields of DisplayPortCalculator to not be
static, so that they could use the Context object from the
constructor. Once refactored, the static context object could be
removed from LibreOfficeMainActivity.
