Neither QMatrix nor QTransform have seen any change since the Qt 5.0 repository import that was related to the underlying math. Only licensing and C++ updates.

Can someone who understands these classes take a look? -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel System Software Products _______________________________________________ Development mailing list Development@qt-project.org https://lists.qt-project.org/listinfo/development
