Testing instructions

1. Open a chart in the EFB and make sure the yellow plane symbol is being shown and moves correctly. Also check that it is shown in the proper location (e.g. SIDS/STARS and Taxi charts)
2. Use the "Fit chart to width" and "Fit chart to height" functionality and verify panning and zooming still works afterwards.

Non-QA Tester

I tested this PR cause Saschl asked me to.

Had the charts freeze on a regulary basis after commit 8676.

Freeze is gone with this PR.

Tested zooming, pushing all buttons ('fit to screen...' was the trigger of the freeze), draged the charts with the mouse. Loaded other charts, pinned them, loaded pinned charts. Deleted them and loaded new ones.

Everthing's working again.

Oh, and the plane symbol is back and on the right place too, of course!

Negatives: none

Testing results: passed.
