Remove dependency on deprecated QtOpenGL module

Open j-o opened this issue 6 years ago • 1 comments

From http://doc.qt.io/qt-5/qglwidget.html:

This class is obsolete. It is provided to keep old source code working.
We strongly advise against using it in new code.

It is only need for QGLWidget::convertToGLFormat, which boils down to a vertical mirror and channel flipping from BGRA to RGBA.
