* Change: In AutoHorizontal::setDuSource() & ::setDuTarget() (& AutoVertical),
check that the requested "du" is less than a pitch (this is not an
upper bound). Issue a warning if not true.
* Change: In AutoSegment::revalidate(), when passing the previous span
interval to expandToMinLength(), if we are in creation stage, make
it empty because it has no sense yet and can lead to a lock in a
too narrow span.
Change the coupled behavior of expandToMinLength() vs.
unexpandToMinLength(), the call to "unexpand" will be done on
AutoSegments that are flagged with SegAtMinArea, instead of
using the return value of "expand". This way we control across
multiple revalidate() if a segment can be "unexpanded".
* Bug: In AutoSegment::expandToMinLength(), not only try to shift left
if we are beyoond the max bound but also to the right if we are
below the min bound.
the span on the target and source were miscalculated, we must
add the half-minimal distance to get the span inside the Track.
* Change: In AutoSegment::isMiddleStack(), rename into isNearMinArea()
as we check for any *small length* set of AutoSegments and not
only the one part of a middle stack. In some rare instances,
two aligned segments can nevertheless be too short.
* Bug: In AutoSegment::reduceDoglegLayer(), when finding a reduced
segment also reset it's duSource & duTarget because it will
no longer be an isolated strip of metal.
* Change: In AutoHorizontal::updateOrient(), when there is a
source/target swap, no need to exchange the dxSource and
dxTarget extentions.
* Change: In AutoHorizontal::setDuSource() & ::setDuTarget(), check
for du bigger than the pitch, which should never occur and
display a warning.
Same modification in AutoVertical.
* Change: In Track::repair(), now invalidate the shifted segments
to ensure cache coherency with the TrackElement.
Do not take AutoSegment in non-preferred direction into
account, and especially do not try to resize them.
Now, invalidate the corrected segments (see below).
* Change: In KatanaEngine::finalizeLayout(), move the track repair
stage from here into NegociateWidow::run(). This way we avoid
the false warning about segment overlap in the data-base final
check. The false warning was because the AutoSegment where
shifted but not invalidated/revalidated leading to a cache
incoherency in the TrackElement. Now they *are* invalidated
and updated.
* Bug: In Track::checkMinArea(), do not check for minimal area when
a segment is overlapping a same net neighbor. To avoid false
minimum area violation warnings.
