Native print dialogs on macOS, Windows and Linux

Use the native print dialogs on macOS, Windows and Linux so users can access the options offered by their selected printer and driver, including paper tray selection, colour or black-and-white printing, duplex printing and print quality where supported.

Desktop applications should gain these dialogs through the existing printing API. Studio's source-code printing should use the same native printing support. Choices made in the dialog must be honoured by the submitted job, including when the user changes printer, paper size or orientation.
