Joachim Henze c947eb4d17 [COMCTL32] Button.c Fix CORE-17260 
Press'n'Hold of a button, then leaving the button rect
should redraw the button in unpressed state

Thanks to JIRA user 'I_kill_Bugs' for perfecting
my initial experiments to fix that.

It regressed by 0.4.9-dev-719-g
b3fb8555bf

No need to sync anything with Wine, their code is
correct on Wine head. The bug was in ros specific diff.
