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 tabbed cutout's slug stays attached while the sheet is cut, but nesting
saw a closed hole and could place parts inside it. Nesting and layout paths
now read material through NestingMaterial.ForNesting, which drops closed
contours with tab spans so the slug counts as part. That covers part
outlines and collision lines, the cutout router, fill expansion, best-fit,
NestLayoutCheck and the GPU bitmaps. Area, overlap diagnostics and cutting
keep the hole, and programs without tabs read exactly as before.

Every plugin engine rebuilt part material from a snapshot by hand and
filtered only rapids, so all three kept counting scribe/etch marks as
material after 1b5e1b1 fixed it in the host. JobPartGeometry is the
validator's own reader made public: SpecialLayers.IsMaterial, validated
closed contours, material area, and TryRead returning null for unreadable
parts. The job validators now use it, so engines and validation agree.
