inlineoverridevirtual |
Whether the driver has a graphical user interface with the end user.
Or in other words, whether we should spawn a thread for world generation and NewGRF scanning so the graphical updates can keep coming. Otherwise progress has to be shown on the console, which uses by definition another thread/process for display purposes.
