NEW/REWORKED: extended the set of functions like JKQTMathTextGetTightBoundingRect(): These use an internal, thread-safe cache and capsule calls to QFontMetricsF-instances. This significantly improves speed in (parallelized) plotting.

made more STATIC data members thread_local or secured them by a std::mutex. This was at least JKQTMathText and JKQTBasePlotter should be usable in several threads
