This project renders an image, and various vertices, lines, polygons using OpenGL.

As noted in comments in the code, QGLWidget is deprecated; since Qt5.4, preferred is QOpenGLWidget: http://doc.qt.io/qt-5/qopenglwidget.html

Turns out a simple s/QGLWidget/QOpenGLWidget/ isn't quite enough.

Observed, when I try that:

loading image, didn't look the same. (Looked same-as-normal after resizing the image).
image went black after clicking a few points.
