The editor branch was written against headers and the PCH, both of which this
branch has done away with, so its own files were ported rather than merged: the
five headers it added are now interface units and their .cpp files module
implementation units.
- editor/{puwg1992,polandmap,turnouts,orthophoto} become eu07.editor.* modules,
application/planpanel becomes eu07.application.planpanel. The plan tool keeps
to its own module rather than joining the eu07.simcore partitions: it stands on
the editor's libraries and eu07.application.uilayer, not on the simulation core,
so :editoruilayer can export import it without a cycle.
- glm arrives by import eu07.glm, never by include, as the rest of the tree does.
maj0sted is header-only and glm-free, so its headers stay includes in the global
module fragment - every unit that names those types includes them itself, since
a global fragment is not visible across units.
- the one textual conflict was :editoruilayer's include block against this
branch's imports; resolved this branch's way plus the planpanel import.
Builds with clang 22 (-DWITH_BETTER_RENDERER=OFF) and starts into the editor on
empty ground with -editor alone.
