- 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. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@20420 a592a061-630c-0410-9148-cb99ea01b6c8
