... which called ::GetActiveProject(), but one purpose of the CommandContext class was to eliminate many uses of that global function, because a CommandContext must always be constructed from a reference to a project (which was always in fact the active one), then passed around to where it is needed! Also, just use the project member directly -- because CommandContext was intended as just a P.O.D (plain-old-data) structure. This also eliminates a dependency of CommandContext.cpp on Project.cpp. This is not enough by itself to break any dependency cycles.
