2D View labels disappear if slice is out of bounds of dose matrix

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Scroll to a slice outside of the dose matrix

What is the expected output? What do you see instead?
The labels should stay on the 2D image. However, they disappear since the 
drawing pipeline gets disrupted since the dose matrix does not exist on the 
slice.

As soon as you scroll back to a slice where the dose matrix exists, the labels 
are restored.

This should be able to be fixed by checking whether the matrix exists before 
starting the drawing pipeline.
