How to test:
Construct two edit widgets.
Enter a long text into the first edit widget, so that the widget autoscrolls.
Click into second (still empty) edit widget.
Click into first edit widget again.
=> Text jums back, so that first character of text in first edit widget is visible again.
This patch keeps the scroll position of the edit widget constant.
Fixed compiler warning by removing unused function nk_sqrt
Fixed compiler warning if you bring your own sin/cos/strtod....
Bump version for breaking nk_sqrt changes
Updated changelog
This caused combo boxes to draw its items before the
panel padding, causing the text to be clipped off.
The code deleted here seems to have been an effort to
solve what 14dd68e solved so it makes sense that these
would conflict. I'm pretty sure 14dd68e is the correct
solution though and this was some old hack.
