\brief The QOpenGLVersionProfile class represents the version and if applicable
the profile of an OpenGL context.
An object of this class can be passed to QOpenGLContext::versionFunctions() to
request a functions object for a specific version and profile of OpenGL.
It also contains some helper functions to check if a version supports profiles
or is a legacy version.
