  Avoid calling time.elapsed() twice in abstract animation
  Adds slowdownFactor to UnifiedTimer in abstract animation
  Add the conversion in-place for QPixmap::fromImageReader() on raster.
  Add QPixmap::fromImageReader() to decode arbitrary images in place.
  Add missing license header.
  Added textureUpload benchmark to the GL benchmarks
  Fixed a crash in menubar with invisible actions
  Fixed ARM .def files.
  Doc: QSettings::sync() imports changes made by other processes.
  Made -graphicssystem trace work with Qt::TextBypassShaping flag.
  Fix an assertion in comp_func_SourceOver_sse2() if const_alpha == 0
  Add a manual test for regular widget interaction with the table.
  New variant of ::createPixmapData with origin for QGraphicsSystem.
