mmm... I think packagers would like to be able to build at the same time both 
gb.qt and gb.qte (./configure --enable-qt --enable-qte ... ) so in the 
sources tree I would create a gb.qte dir and copy the gb.qt/src dir to 
gb.qte/src during configure or better symlink all the common sources so the 
packager won't be misled by the src dir being recreated/overwritten.

A look at qt-embedded sources shows that 72 or 75 values are assumed to 
generate fonts. I think 72 dpi is related to printing so I would assume a 
value of 75 for display resolution.

Ok, thanks a lot!
