[Texmacs-dev] Missing #include <QPainterPath>

[Sebastian Miele]

When compiling the current master branch of github:texmacs/texmacs, I
got

   error: aggregate ‘QPainterPath pp’ has incomplete type and cannot
   be defined

on two files (src/Plugins/Qt/QTMStyle.cpp and
src/Plugins/Qt/qt_renderer.cpp). After adding

   #include <QPainterPath>

to both files, it works. My system has only Qt5, no Qt4. But according
to https://doc.qt.io/archives/qt-4.8/qpainterpath.html, it should be
correct for Qt4, too.
