    Description

      We should update & document the dependency of Qt WebEngine on OpenGL in one central place.

      The overview documentation currently states:

      Note: The Qt WebEngine Widgets module uses the Qt Quick scene graph to compose the elements of a web page into one view. This means that the UI process requires OpenGL ES 2.0 or OpenGL 2.0 for its rendering.

      Which is actually wrong. We also support software rendering via ANGLE or software rasterizer by setting either the QT_QUICK_BACKEND environment variable, call QQuickWindow::setSceneGraphBackend, or passing -device= to the command line. Furthermore, we support rendering through MESA (opengl32sw.dll) if AA_UseSoftwareOpenGL is set, and support enabling WebGL then if -enable-webgl-software-rendering is set.

      Since this is a common request, this should be documented.
