lyx_mirror/src/mathed/InsetMathSpace.h
Abdelrazak Younes 24c8ca10d2 Trying to solve bug-2452, I optimized some of the most significant problems outlined in the profile report attached in there.
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.
