Subject: [PATCH] limit Interpret() for dirty cells only to the given row range
(bsc#1197497)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
ScColumn::InterpretDirtyCells() already takes a row range, and Interpret()
can take a range inside a formula group, so don't lose the information
in DirtyCellInterpreter, otherwise a whole large formula could be
interpreted when just a subset would be enough.

Subject: [PATCH] try to limit cell interpreting to only visible cells when
drawing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If there's a document with a huge formula group, InterpretDirtyCells()
on load will only interpret the range needed for drawing. But then
scrolling just a bit could result in e.g. IsValue() call on a cell,
and that could result in unrestricted Interpret() on the whole
huge formula group, which could be slow. So explicitly interpret
just the drawn cells in the hope that it'll avoid any further
Interpret() calls.
