9de0b4396b solidify/Makefile (LDFLAGS): rename to LDLIBS 
The obsolete use of LDFLAGS for libraries caused the build to fail.

671b74d81c cameo/templates/mkmk-simple: make $NAME.drl optional 
pcbnew will not generate a drill file if the board that has neither
vias nor through-hole pads, so we shouldn't insist on it existing
either.

0fc785d3a1 cameo/fped2stl.pl: hack: maintain decimal point across flipping 
Since our regexps expect numbers to contain a decimal point, any result
that was an integer tripped the re-match after flipping. This hack works
around the problem by formatting the result such that it also has a decimal
point.

033d55c8ad cameo/zstack.pl: output one point at (x, y, z0) to set reference level 
Otherwise, gp2rml will eliminate any offset. (x, y) is an arbitrary point
from the toolpaths.

e62da4e2bb cae-tools/cameo/fped2stl.pl (flush): substitute coordinates only once 
If a layer was at exactly z = 1 mm, we would set it to $z1 (after temporarily
setting it to $z) even in cases where it should be at $z.

b8c927831f cameo/templates/mkmk-simple: support new edge file names

9a6772f79d cameo/templates/mkmk-simple: use "set size ratio -1", not "set size ratio square" 
"ratio -1" produces a 1:1 ratio of the units (which is what we want) while
"ratio square" makes the xrange and yrange the same size, whatever that's
supposed to be good for.

c73509dacc cameo/fped2d2z.pl: new option -t Zmax to set the height of the workpiece 
This is similar to -r, except that we don't swap X and Y, and we use
the specified value instead of searching for the maximum in the input
data.

53fe70950d poly2d/: try to work around spurious aborts in CGAL::create_interior_skeleton_and_offset_polygons_with_holes_2 
cameo encountered spurious aborts with the following message:

  terminate called after throwing an instance of 'CGAL::Precondition_exception
  what():  CGAL ERROR: precondition violation!
  Expr: is_simple_2(first, last, traits)
  File: /usr/include/CGAL/Polygon_2/Polygon_2_algorithms_impl.h
  Line: 420

These aborts come and go even if just the coordinate origin is slightly
changed. Setting CGAL_POLYGON_NO_PRECONDITIONS in p2d_area_holes.cpp
made them go away in some cases, but cameo could still run into an
assertion violation (in CGAL).

We now check all the polygons, outer boundary and holes, being sent to
CGAL::create_interior_skeleton_and_offset_polygons_with_holes_2 for
simplicity, and stop recursing if there is any hint of a problem.

This seems to avoid trouble for now, but the issue deserves further
investigation.
