Gcc 4.7 warns that this kind of narrowing is illegal in C++11, so we can just as well fix that right now. In GuiFontMetrics this is fixed by chaning the types in the AscendDescend struct from short int to int. In ParagraphMetrics it is fixed by addint explicit casts. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@40586 a592a061-630c-0410-9148-cb99ea01b6c8
