Fix #4996

@helenayele - I think you're aware of both of the issues resolved here. Would you mind testing please?

1. In this fix, we only export the visible part of the track
   
2. But the end time on exported pdf and on time controller is not the same.
   See the end time on time controller: it is 5:26
   

The end time on exported pdf looks is 5:20

can you please fix this?

Good morning. Could you specify the steps to generate that PDF?
Somehow I tried the same, but it works as expected in my computer.

Steps to reproduce ;

1. Open the PlotWithGeoTiff.dpf file
2. Change small step to 5 minutes
3. Export to pdf file
