Fix the issue of segmentation fault when the pattern of a mbe is not setted.
For Skia graphic engine, a mbe does not always have a pattern. For
example, a color paint does not set a pattern on a mbe for a shape.
So, we check if pattern is setted before accessing it.

* Add loopback reference from rdman to the backend. This is only required when we need to acquire the tman for the animation. This is not a reasonable arrangement since the animation should be backend transparent. We should not touch the backend directly from the animation. We should relocate the tman to the rdman.
