master 05a022c36e: Fix calculation of default highlightForeground in the lucid menu bar

[Po Lu]

branch: master
commit 05a022c36e4177842dd6a4f3e24c2ed1776dbb66
Author: Po Lu <luangruo@yahoo.com>
Commit: Po Lu <luangruo@yahoo.com>

    Fix calculation of default highlightForeground in the lucid menu bar
    
    * lwlib/xlwmenu.c (xlwMenuResources, display_menu_item)
    (make_drawing_gcs, make_shadow_gcs, openXftFont, XlwMenuRealize)
    (XlwMenuSetValues): Use -1 as the default for
    highlight_foreground.  Replace that with the normal foreground
    when creating GCs.  Reported by Colin Baxter
    <m43cap@yandex.com>.
