No Mac monospace face carries the Braille Patterns block, so Terminal --
which falls back generously rather than drawing a box -- borrows the
charts and the map's terrain from a proportional face and lands them at
the wrong width. Nothing announces itself as broken; it is just crooked,
and a reader with nothing to compare against never finds out why.
Fixing it means a font, and a font means a profile. The question that
shapes this module is whose terminal it is. MeshTerm's palette is the
16-colour VT set, crude on purpose, and nobody should have to read their
mail in it -- so nothing here touches the default profile or edits their
preferences. It adds a profile named MeshTerm and opens our own window in
it; theirs keeps its translucency, and quitting leaves nothing behind.
That is also the only route that works at all. Terminal rewrites its
preferences from memory when it quits, so a file written while it runs --
and MeshTerm always runs inside it -- is discarded later. Handing Terminal
a .terminal file lets Terminal do the importing.
The profile is generated from _VT_SLOTS rather than shipped, so the window
cannot disagree with the screen it holds. The NSColor and NSFont archives
are pinned to bytes read back off a profile that was installed on a real
Mac and confirmed rendering, not to a reading of the format.
relaunch.py is the half that was never Windows-specific -- own_command,
child_environment and its _PYI trap, the wanted size -- moved out of
winterminal so both terminals share one copy.
Not yet wired into startup: the launch itself wants a Mac to confirm, and
that machine is asleep.
