- get rid of the cached Dimension. Text inset dimensions are saved in ParagraphMetrics and mathed maintain their own dimension where needed.
- width(), ascent(), descent(): deleted.
- dimension(): now needs a valid BufferView.
- metrics(): now void.
* BufferView::getCoveringInset(): simplify.
* ParagraphMetrics(): now cache inset dimensions.

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.
