lyx_mirror/src/insets/InsetFlex.cpp
Abdelrazak Younes 237c132c1e * Inset:
- 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.
