gui_toolkit 0.46.0

Added

• platform.Event.injected: an event made by inject_event (a test, a remote control, a macro) says so; an application that reads the pointer's position from the system (a window dragged across the screen) uses the event's own position for these, as the real pointer is elsewhere.
• Build_Params.inactive, ui.inactive: a window that is not the one the user is in is built with inactive = true: its focused line and text edits keep the focus but draw no caret and ask for no wake to blink it (an application with several windows no longer blinks a caret in each).
