This commit avoids unnecessary metrics recalculations by caching the last LyXFont used. I had to cleanup the width(), ascent() and descend() redundancies by transferring that to InsetBase. InsetMathDim should go now as it is not really needed. * InsetBase: properly handle inset Dimension. * InsetOld: get rid of redundant width(), ascent() and descent() * InsetMathDim: ditto * InsetMathChar::metrics(): avoid metrics recalculation if font is unchanged. * InsetMathSymbol::metrics(): ditto * InsetMathKern: use InsetBase::dim_ instead of local ones. * InsetMathSpace: - use InsetBase::dim_ instead of local ones. - space to width transformation transferred to anonymous namespace. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@17899 a592a061-630c-0410-9148-cb99ea01b6c8
