Description of the Issue

When we resize NPP main window then scrolling view to the end by -n or -p argument doesn't work properly.

Steps to Reproduce the Issue

1. Open NPP and resize main window (for example to 1024x703).
2. Close NPP.
3. Make test for stylers.model.xml file (it has 1407 lines and 170624 length)

notepad++ -n1407 stylers.model.xml
notepad++ -n1500 stylers.model.xml

notepad++ -p170624 stylers.model.xml
notepad++ -p180000 stylers.model.xml

We get cursor in right place, but view stick on 1401 line (when mian window size is 1024x703).

I don't know if it's a bug or intentional but if we want jump to last line/char (or we pass greater value than them) then NPP at least should force scrolling view to the end (as much as possible).
