/**
* This service enables embedders to implement their own Print and Progress Dialogs.
* Each platform has a "base" or "basckstop" implementation of the service. The
* service is automatically registered at start up.
*
* Historically, platform toolkits with native dialogs have implemented them in the GFX layer
* Usually they were displayed when a new DeviceContextSpec specific to that platform
* was created.
*
* Windows: The GFX layer no longers supports default toolkit behavior for displaying the
* native Print Dialog.
* If an embedder implemented service returns any error code (other than NS_ERROR_ABORT)
* printing will terminate.
*
* Returning NS_OK assumes that the PrintSettings object was correctly filled in and
* if it does not have valid fields for printer name, etc. it may also terminate.
*
* Defaults for platform service:
* showPrintDialog - displays a native dialog
* showPageSetup - displays a XUL dialog
* showProgress - displays a XUL dialog
* showPrinterProperties - n/a
*
* Summary for Windows Embedders:
* Stated once again: There is no "fallback" native platform support in GFX for the
* displaying of the native print dialog. The current default implementation for Windows
* display a native print dialog but a XUL-based progress dialog.
* If you wish to have a native progress dialog on Windows you will have to create and
* register your own service.
*
* Note: The Windows version Mozilla implements this service which is
* automatically built and registered for you. You can use it as an example.
* It is located at "mozilla/embedding/components/printingui/win". That service
* is capable of displaying a native print dialog and a XUL progress dialog.
*
* To fly your own dialog you may:
*
* 1) Implement this service to display at least the Print Dialog and a Print Progress Dialog
* or you may implement just one of the dialogs and pass back NS_ERROR_NOT_IMPLEMENTED
* for any of the others.
*
* 2) For the Print Dialog:
* You may stub out this service by having all the methods return NS_ERROR_NOT_IMPLEMENTED.
* You can then fly you own dialog and then properly fill in the PrintSettings object
* before calling nsIWebBrowserPrint's Print method. If you stub out this service
* you MUST set "printSilent" to true, if you do not, Printing will terminate and an
* error dialog will be displayed.
*
* Mac: The GFX layer still supports default toolkit behavior for displaying the Print Dialog.
* If an embedder implemented service returns NS_ERROR_NOT_IMPLEMENTED for "showPrintDialog"
* The toolkit will display the native print dialog.
*
* Defaults for platform service:
* Mac OS9: showPrintDialog - displays a native dialog
* showPageSetup - displays a native dialog
* showProgress - displays a XUL dialog
* showPrinterProperties - n/a
*
* Mac OSX: showPrintDialog - displays a native dialog
* showPageSetup - displays a native dialog
* showProgress - not implemented (provided by OS)
* showPrinterProperties - n/a
*
* GTK: There are no native dialog for GTK.
*
* Defaults for platform service:
* showPrintDialog - displays a XUL dialog
* showPageSetup - displays a XUL dialog
* showProgress - displays a XUL dialog
* showPrinterProperties - displays a XUL dialog
