  -----------
  VideoVisualMonoScope: Improve OpenGL performance

- as for the Vulkan implementation, use a series of vertex buffers for
different lines instead of ping-ponging to a framebuffer object
- improves performance and fixes rendering of the visualisation over
video

  MythVisualMonoScopeOpenGL: Don't use viewport for zoom effect

- it breaks under various scenarios
- use a transform instead - which is probably faster anyway
