[Libreoffice] Lines to remove in fontworkgallery.cxx ?

[julien]

Hello,

In the file libs-core/svx/source/tbxctrls/fontworkgallery.cxx, can these 
lines be removed completely ?
bool bHighContrast = GetSettings().GetStyleSettings().GetHighContrastMode();

I saw warnings about bHighContrast not used in 2 parts of this file, but 
i don't know if the whole lines can be removed.
The variable can obviously be removed but does the rest of line 
initialize something ? I can't find information about this.
