The ViewerGLWidget would receive raw GLuint textures while most of Olive uses
an OpenGLTexture C++ wrapper. Unfortunately this would lead to the C++ wrapper
getting destroyed since its instance wasn't kept in the ViewerGLWidget. This
meant by the time the ViewerGLWidget would re-draw, the texture would have
already been destroyed leading to some black frames. This is now fixed.
