No functional changes

DX9 → DX11 migration

DX9 → DX11 migration

The rendering backend was switched from DirectX 9 to DirectX 11 to fix ImGui window creation failures on systems where DX9 device creation fails (reported by an end-user with Intel UHD Graphics 630).

The tool is functionally the same v1 - v4.

Standalone executable for testing window loading and backend rendering on machines that do not have Alibre Design installed.

Fallback Simple UI Command

Added fallback Win32 window, command "Measure Lengths Simple UI"
