Dropping the parts that land on a clamp suits small parts, which fill the
gaps between clamps. Large parts often do better if the fill area stops
short of the clamps. The rows still fit, and no part is lost on a clamp.
When every clamp in the fill area lies on one edge, interactive Fill now
also fills the area with that edge moved just past the clamp keep-outs,
as a larger edge spacing would. It keeps whichever layout the strategy's
comparer ranks better, and a tie keeps the dropped-parts layout. Clamps
on more than one edge skip the comparison. The second fill reuses the
cached best-fit pairs. While it runs, a preview counts as the new best
only when it beats the first layout, so the preview never gets worse.

Interactive Fill on a plate with clamps used to split the plate into
clamp-free rectangles and fill each one separately. It showed no progress,
so Accept did nothing until the end, and Stop discarded the result. Packing
around the clamps also tends to give a worse layout than losing the few
parts that land on them.
FillItem and FillGroup now fill the area as if there were no clamps. They
then drop each part that enters a clamp keep-out or sits too close to an
existing part, using the same check as before. For a multi-part group, the
whole copy is dropped when any member fails. Progress previews are filtered
by the same check, so a layout accepted early is clamp-clear. A quantity
request that loses copies asks for that many more, up to two more times.
Pack and whole-plate Nest still pack only into the clamp-free areas.
