We introduced WrapOpenGL to link against either desktop GL or GLESv2
depending on the GL feature in QtGui. This works "fine", with two
caveats:
(1) find_package(WrapOpenGL) must be called after
find_package(Qt5Gui) in order for the feature check in
FindWrapOpenGL.cmake to work. That's error prone.
(2) More and more places are popping up, in particular examples,
where GL linkage is required due to inline functions in Qt that
forward to GL functions - such as on Android.
This in particular explains the qmake behavior of making the GL
linkage (desktop _or_ GLES) a public dependency of QtGui, so only
Gui linkage is required.
Those two aspects combined are the nail in the coffin of FindWrapOpenGL
and it would seem much easier to simply make the Desktop GL vs. GLES
decision once in Gui's CMakeLists.txt and let Qt5GuiDependencies.cmake
propagate this well. This allows us to get rid of plenty of special
cases as well.

Qt is provided with a comprehensive canvas through the GraphicsView classes. These examples demonstrate the fundamental aspects of canvas programming with Qt. Documentation for these examples can be found via the Examples link in the main Qt documentation.
