Support bitmap PDF export for Redaction
* Add a new parameter IsRedactMode (SID_IS_REDACT_MODE) to .uno:ExportDirectToPDF
* Make sure the new param makes it into PDFExport as part of FilterData
* Hijack the metafile before being sent to ImplExportPage(), convert to bitmap, and replace the original
* Add a new entry to GenericCommands.xcu to make our button with param visible
* Nitpick: For things to be included in the bitmap conversion,
they need to be added to the metafile before the conversion
in PDFExport::ExportSelection(). Things added after that point
(inside ImplExportPage() for example) will not be bitmapped/pixelized
