DJ VCAM 1.2.9 production - DirectShow LGPL replacement/relink materials

The exact LGPL library sources and matching x64/x86 OBJ/RES application
inputs accompany the binaries. Auth/Rust implementation, credentials and
PDBs are excluded. Six LGPL translation units can be rebuilt while fourteen
application inputs remain unchanged.

From the matching MSVC 19.50 x64-host developer PowerShell:
  .\Rebuild-Lgpl.ps1 -Architecture x64 -OutputDirectory C:\a-new-directory
Use the matching x64-to-x86 shell and -Architecture x86 for 32-bit output.

DJVCAM_PRODUCTION_RELEASE=1 and DJVCAM_SLOT_DIAGNOSTICS=0 are required for
the supplied production object layouts. Private performance profiling is 0.
Do not mix diagnostic-candidate objects or headers into this kit.

-ProofMarker adds an inert export to a rebuilt LGPL unit only. The marker
is absent from product DLLs. Relinking/inspection does not invoke the DLL
entry point, register a camera, operate accounts or install anything.
