Avoid missing paints when resizing GV with QOpenGLWidget viewport
There is nothing guaranteeing there will be a paint request after
resizeViewportFramebuffer() is called. However we must not be left
with a framebuffer with uninitialized content. So trigger an update.
Include also a half-hearted autotest. QOpenGLWidget (or QGLWidget)
viewports have not been autotested at all. Try to verify that it
is functional at least, even if we cannot check the actual output.
