566 
567             Support of MetaCommentActions in the VclMetafileProcessor2D
568             Found MetaCommentActions and how they are supported:
569 
570             XGRAD_SEQ_BEGIN, XGRAD_SEQ_END:
571 
572 			Used inside OutputDevice::DrawGradient to mark the start and end of a MetaGradientEx action.
573             It is used in various exporters/importers to have direct access to the gradient before it
574             is rendered by VCL (and thus fragmented to polygon color actions and others). On that base, e.g.
575             the Metafile to SdrObject import creates it's gradient objects.
576             Best (and safest) way to support it here is to use PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
577             map it back to the corresponding tools PolyPolygon and the Gradient and just call
578             OutputDevice::DrawGradient which creates the necessary compatible actions.
579 
580             XPATHFILL_SEQ_BEGIN, XPATHFILL_SEQ_END:
581 
582 			Two producers, one is vcl/source/gdi/gdimtf.cxx, line 1273. There, it is transformed
583             inside GDIMetaFile::Rotate, nothing to take care of here.
584             The second producer is in graphics/svx/source/svdraw/impgrfll.cxx, line 374. This is used
585             with each incarnation of Imp_GraphicFill when a metafile is recorded, fillstyle is not
586             XFILL_NONE and not completely transparent. It creates a SvtGraphicFill and streams it
587             to the comment action. A closing end token is created in the destructor.
588 			Usages of Imp_GraphicFill are in Do_Paint_Object-methods of SdrCircObj, SdrPathObj and
589 			SdrRectObj.
590             The token users pick various actions from SvtGraphicFill, so it may need to be added for all kind
591             of filled objects, even simple colored polygons. It is added as extra information; the
592             Metafile actions between the two tokens are interpreted as output generated from those
593             fills. Thus, users have the choice to use the SvtGraphicFill info or the created output
594             actions.
595             Even for XFillTransparenceItem it is used, thus it may need to be supported in
596             UnifiedTransparencePrimitive2D, too, when interpreted as normally filled PolyPolygon.
597 			Implemented for:
598 				PRIMITIVE2D_ID_POLYPOLYGONGRAPHICPRIMITIVE2D,
599 				PRIMITIVE2D_ID_POLYPOLYGONHATCHPRIMITIVE2D,
600 				PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
601 				PRIMITIVE2D_ID_POLYPOLYGONCOLORPRIMITIVE2D,
602 				and for PRIMITIVE2D_ID_UNIFIEDTRANSPARENCEPRIMITIVE2D when detected unified transparence
603 
604             XPATHSTROKE_SEQ_BEGIN, XPATHSTROKE_SEQ_END:
605 
606 			Similar to pathfill, but using SvtGraphicStroke instead. It also has two producers where one
607 			is also the GDIMetaFile::Rotate. Another user is MetaCommentAction::Move which modifies the
608 			contained path accordingly.
609 			The other one is SdrObject::Imp_DrawLineGeometry. It's done when MetaFile is set at OutDev and
610 			only when geometry is a single polygon (!). I see no reason for that; in the PS exporter this
611 			would hinder to make use of PolyPolygon strokes. I will need to add support at:
612 				PRIMITIVE2D_ID_POLYGONHAIRLINEPRIMITIVE2D
613 				PRIMITIVE2D_ID_POLYGONSTROKEPRIMITIVE2D
614 				PRIMITIVE2D_ID_POLYGONSTROKEARROWPRIMITIVE2D
615 			This can be done hierarchical, too.
616 			Okay, base implementation done based on those three primitives.
617 
618             FIELD_SEQ_BEGIN, FIELD_SEQ_END
619 
620             Used from slideshow for URLs, created from diverse SvxField implementations inside
621             createBeginComment()/createEndComment(). createBeginComment() is used from editeng\impedit3.cxx
622             inside ImpEditEngine::Paint.
623             Created TextHierarchyFieldPrimitive2D and added needed infos there; it is an group primitive and wraps
624             text primitives (but is not limited to that). It contains the field type if special actions for the
625 			support of FIELD_SEQ_BEGIN/END are needed; this is the case for Page and URL fields. If more is
626 			needed, it may be supported there.
627             FIELD_SEQ_BEGIN;PageField
628             FIELD_SEQ_END
629             Okay, these are now completely supported by TextHierarchyFieldPrimitive2D. URL works, too.
630 
631             XTEXT
632 
633             XTEXT_EOC(i) end of character
634             XTEXT_EOW(i) end of word
635             XTEXT_EOS(i) end of sentence
636 
637             this three are with index and are created with the help of a i18n::XBreakIterator in
638             ImplDrawWithComments. Simplifying, moving out text painting, reworking to create some
639             data structure for holding those TEXT infos.
640             Supported directly by TextSimplePortionPrimitive2D with adding a Locale to the basic text
641             primitive. In the MetaFileRenderer, the creation is now done (see below). This has the advantage
642             that this creations do not need to be done for all paints all the time. This would be
643             expensive since the BreakIterator and it's usage is expensive and for each paint also the
644             whole character stops would need to be created.
645             Created only for TextDecoratedPortionPrimitive2D due to XTEXT_EOL and XTEXT_EOP (see below)
646 
647             XTEXT_EOL() end of line
648             XTEXT_EOP() end of paragraph
649 
650             First try with boolean marks at TextDecoratedPortionPrimitive2D did not work too well,
651 			i decided to solve it with structure. I added the TextHierarchyPrimitives for this,
652 			namely:
653 			- TextHierarchyLinePrimitive2D: Encapsulates single line
654 			- TextHierarchyParagraphPrimitive2D: Encapsulates single paragraph
655 			- TextHierarchyBlockPrimitive2D: encapsulates object texts (only one ATM)
656 			Those are now supported in hierarchy. This means the MetaFile renderer will support them
657 			by using them, reculrively using their content and adding MetaFile comments as needed.
658 			This also means that when another text layouter will be used it will be necessary to
659 			create/support the same HierarchyPrimitives to support users.
660 			To transport the information using this hierarchy is best suited to all future needs;
661 			the slideshow will be able to profit from it directly when using primitives; all other
662 			renderers not interested in the text structure will just ignore the encapsulations.
663 
664             XTEXT_PAINTSHAPE_BEGIN, XTEXT_PAINTSHAPE_END
665 			Supported now by the TextHierarchyBlockPrimitive2D.
666 
667             EPSReplacementGraphic:
668 			Only used in goodies\source\filter.vcl\ieps\ieps.cxx and svx\source\xml\xmlgrhlp.cxx to
669 			hold the original EPS which was imported in the same MetaFile as first 2 entries. Only
670 			used to export the original again (if exists).
671 			Not necessary to support with MetaFuleRenderer.
672 
673             XTEXT_SCROLLRECT, XTEXT_PAINTRECT
674 			Currently used to get extra MetaFile infos using GraphicExporter which again uses
675 			SdrTextObj::GetTextScrollMetaFileAndRectangle(). ATM works with primitives since
676 			the rectangle data is added directly by the GraphicsExporter as comment. Does not need
677 			to be adapted at once.
678 			When adapting later, the only user - the diashow - should directly use the provided
679 			Anination infos in the appropriate primitives (e.g. AnimatedSwitchPrimitive2D)
680 
681             PRNSPOOL_TRANSPARENTBITMAP_BEGIN, PRNSPOOL_TRANSPARENTBITMAP_END
682 			VCL usage when printing PL -> THB. Okay, THB confirms that it is only used as
683 			a fix (hack) while VCL printing. It is needed to not downscale a bitmap which
684 			was explicitely created for the printer already again to some default maximum
685 			bitmap sizes.
686 			Nothing to do here for the primitive renderer.
687 
688 			Support for vcl::PDFExtOutDevData:
689 			PL knows that SJ did that stuff, it's used to hold a pointer to PDFExtOutDevData at
690 			the OutDev. When set, some extra data is written there. Trying simple PDF export and
691 			watching if i get those infos.
692 			Well, a PDF export does not use e.g. ImpEditEngine::Paint since the PdfFilter uses
693 			the SdXImpressDocument::render and thus uses the VclMetafileProcessor2D. I will check
694 			if i get a PDFExtOutDevData at the target output device.
695 			Indeed, i get one. Checking what all may be done when that extra-device-info is there.
696 
697 		    All in all i have to talk to SJ. I will need to emulate some of those actions, but
698 			i need to discuss which ones.
699 			In the future, all those infos would be taken from the primitive sequence anyways,
700 			thus these extensions would potentially be temporary, too.
701             Discussed with SJ, added the necessary support and tested it. Details follow.
702 
703 			- In ImpEditEngine::Paint, paragraph infos and URL stuff is added.
704 			  Added in primitive MetaFile renderer.
705 			  Checking URL: Indeed, current version exports it, but it is missing in primitive
706 			  CWS version. Adding support.
707 			  Okay, URLs work. Checked, Done.
708 
709             - UnoControlPDFExportContact is only created when PDFExtOutDevData is used at the
710 			  target and uno control data is created in UnoControlPDFExportContact::do_PaintObject.
711 			  This may be added in primitive MetaFile renderer.
712 			  Adding support...
713 			  OOps, the necessary helper stuff is in svx/source/form/formpdxexport.cxx in namespace
714 			  svxform. Have to talk to FS if this has to be like that. Especially since
715 			  ::vcl::PDFWriter::AnyWidget is filled out, which is already part of vcl.
716 			  Wrote an eMail to FS, he is on vacation currently. I see no reason why not to move
717 			  that stuff to somewhere else, maybe tools or svtools ?!? We will see...
718               Moved to toolkit, so i have to link against it. I tried VCL first, but it did
719               not work since VCLUnoHelper::CreateFont is unresolved in VCL (!). Other then the name
720               may imply, it is defined in toolkit (!). Since toolkit is linked against VCL itself,
721               the lowest move,ment plave is toolkit.
722               Checked form control export, it works well. Done.
723 
724 		    - In goodies, in GraphicObject::Draw, when the used Graphic is linked, infos are
725 			  generated. I will need to check what happens here with primitives.
726 			  To support, use of GraphicPrimitive2D (PRIMITIVE2D_ID_GRAPHICPRIMITIVE2D) may be needed.
727 			  Added support, but feature is broken in main version, so i cannot test at all.
728 			  Writing a bug to CL (or SJ) and seeing what happens (#i80380#).
729               SJ took a look and we got it working. Tested VCL MetaFile Renderer based export,
