  MythOpenGLPainter: Optimise rendering reference counted MythImages

- screens that reuse the same image multiple times trigger GPU stalls as
the Vertex Buffer Object is still in use from the previous rendering.
- avoid stalls by tracking when we are displaying the same image
multiple times in a single render pass and use an alternate, pooled
Vertex Buffer Object.
- does not work 100% of the time but reduces warnings by roughly 90%.

  MythMainWindow: Don't delete the render device on exit

- it causes intermittent seg faults
- but ensure OpenGL resources are released
- also add some more GPU debug markers for analysis
