Tag #1375
IsSelectionEditable should check whether the focus node and anchor node
aren't null before trying to use them.
This also changes the initialization of selections' aOutIndex to the
last range in the selection as a fallback in case we don't add a range
later (in AddItem) which could also end up with a null selection
otherwise if the additional selection nodes are removed.
Since we are using vsync for timing anyway in the layout refresh driver,
there is no need to bump the system timer resolution down to 1 ms.
This resolves#1507.
whether they should be drawn.
This reduces the size of display lists for tables by only adding display
list items that are actually going to be visibly drawn, which will help
overall performance of table drawing.
There were actually two separate logical errors in this method:
The first part is that "origSizes.isSome()" is simply a bogus
requirement for applying min/max-sizes here. I'm still keeping
the optimization of not needlessly copying the mSizes array
(as originally intended) since it's a quite common case.
The second bug is that min/max-sizes were only applied under
the "if (fr != 0.0f)" block. This is bogus since the calculated
'fr' value depends on 'aAvailableSize' which might change by
applying min/max-sizes and thus 'fr' could become non-zero in
the second round.
To fix, this patch just moves "applyMinMax" block out one level.
This stub is added because websites insist on considering this
very hardware-dependent and O.S.-variable low-level font-control
as a "critical feature" which it isn't as there is 0 guarantee
that font variation settings are supported or honored by any
operating system used by the client.
On top this is a WD status feature that sites shouldn't be using, and
the feature itself is strongly discouraged for use in favor of standard
CSS font manipulation keywords like `font-weight`.
Do less work in PaintRowGroupBackgroundByColIdx for cells that are not in our desired set of columns.
crash fix:
Guard against empty column groups when building a display list for a table.
