commit fe0ef5c02abde14d2a7d309c1e0f4d455884d4eb
Author: Jean-Marc Lasgouttes <[email protected]>

Force metrics calculation when entering a previewed inset
The safe part:
- change notifyCursorEnters to use two parameters (it was not yet used)
- in previewed insets, force a metrics computation when entering the inset
The less obvious part:
- in BufferView::dispatch(), copy the cursor screenUpdate() flags to
the DispatchResult parameter of the method after calling
notifyCursorLeavesOrEnters().
- In BufferView::processUpdateFlags() do the SinglePar update thing
even when ForceDraw is required. I *think* this made sense when
ForceDraw was added after computing metrics with Force, but that
this is not needed anymore because we use if/else.
Fixes bug #13225.
