Subject: Use windowShouldClose rather than windowWillClose
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgui.git;a=commitdiff_plain;h=b1dbcb05d3ec43654d78e2662ae22162561c8270

Use windowShouldClose rather than windowWillClose

This prevents a crash when the autorelease pool is released (no clue what
exactly goes wrong) and allows the application to decide whether to close
the window or not.
