lok: handle mouse/keyboard events in Math embedded in Impress/Draw

Since Impress/Draw use mm100, we need to convert object area that
SfxInPlaceClient provides, which is in parent units, into twips.
TODO: how would taking the units from object shell with Calc, given
that it does not call SetMapUnit in ScDocShell ctor?
