[Werner LEMBERG]

branch: master
commit 3be74494a28c211c7b000d6cba8ef17f82720c8b
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>

    [ftinspect] Refine signal for HintingModeComboBox.
    
    * src/ftinspect.cpp (MainGUI::checkHintingMode): Grey out `slight'
    hinting item in antiAliasingComboBox if not in auto-hinting mode.
    Also set a different anti aliasing value for this case if `slight'
    was the current value.
    
    * src/ftinspect.h: Updated.
