Geometry, nesting and import code now call PortableMath instead of
System.Math for Sin, Cos, Tan, Atan, Atan2, Asin and Acos (Core, Engine,
IO, Data; 269 calls in 64 files). A test fails if those projects call the
runtime's trig again.
With the runtime's trig, Windows and Linux disagreed in the last bit at
non-quarter angles and the same job could nest differently: the
learned-angle nests (a cross fixture) placed 23 parts in Strip on Windows
and 28 on Linux. Now every Engine.Tests pin gives the same layout on both
(3600 passing on Linux and on DesktopPC), Linux layouts are unchanged, and
the learned-angle rows are re-pinned to the shared layouts, which pass the
overlap and work-area checks, and run on every platform again.
Fixes Project Memory 518f3b58.
A closed contour around its center with at least 270 degrees of arc on
one center and radius now counts as a keyed hole, in its own row after
round holes of that diameter. Curved slots stay out: their long arcs wrap
around solid material, so the center is outside the contour.

Holes and radii need sizes on the drawing as well as the overall extents. Select
circles or arcs, right-click and choose Add Radius Dimension or Add Diameter
Dimension. The value is measured live from the curve, found by its entity ID, so
it follows edits; only the leader angle and label offset are saved. A radius on
an arc stays on its sweep, and labels are kept clear of the curve and center.

Extension lines started at the extents' corners, which float in empty space on
angled or irregular parts. They now run from the dimension line toward the part
until they first meet the profile offset by a fixed screen gap, so they reach
the feature they measure without touching it at any angle.

Shops need a part's overall size on the drawing while converting it. Width and
height are measured live from the geometry that will be cut, so they follow
filters, exclusions, simplifying, breakoffs and tabbed cutouts instead of going
stale. Only the placement is saved; dimensions never touch the program.
