ShellToolRegistrar typedef
ShellToolRegistrar =
VoidCallback Function(bool select(FloorPlanTool tool))
Registers the shell's tool selector with its host (host embedding API
spec C-3, S-6): select activates a tool when the shell's capabilities
allow it and answers whether it did. Returns the withdrawal, which the
shell calls on dispose, as ShellSettleRegistrar's.
Implementation
typedef ShellToolRegistrar = VoidCallback Function(
bool Function(FloorPlanTool tool) select);
