561 
562             Support of MetaCommentActions in the VclMetafileProcessor2D
563             Found MetaCommentActions and how they are supported:
564 
565             XGRAD_SEQ_BEGIN, XGRAD_SEQ_END:
566 
567 			Used inside OutputDevice::DrawGradient to mark the start and end of a MetaGradientEx action.
568             It is used in various exporters/importers to have direct access to the gradient before it
569             is rendered by VCL (and thus fragmented to polygon color actions and others). On that base, e.g.
570             the Metafile to SdrObject import creates it's gradient objects.
571             Best (and safest) way to support it here is to use PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
572             map it back to the corresponding tools PolyPolygon and the Gradient and just call
573             OutputDevice::DrawGradient which creates the necessary compatible actions.
574 
575             XPATHFILL_SEQ_BEGIN, XPATHFILL_SEQ_END:
576 
577 			Two producers, one is vcl/source/gdi/gdimtf.cxx, line 1273. There, it is transformed
578             inside GDIMetaFile::Rotate, nothing to take care of here.
579             The second producer is in graphics/svx/source/svdraw/impgrfll.cxx, line 374. This is used
580             with each incarnation of Imp_GraphicFill when a metafile is recorded, fillstyle is not
581             XFILL_NONE and not completely transparent. It creates a SvtGraphicFill and streams it
582             to the comment action. A closing end token is created in the destructor.
583 			Usages of Imp_GraphicFill are in Do_Paint_Object-methods of SdrCircObj, SdrPathObj and
584 			SdrRectObj.
585             The token users pick various actions from SvtGraphicFill, so it may need to be added for all kind
586             of filled objects, even simple colored polygons. It is added as extra information; the
587             Metafile actions between the two tokens are interpreted as output generated from those
588             fills. Thus, users have the choice to use the SvtGraphicFill info or the created output
589             actions.
590             Even for XFillTransparenceItem it is used, thus it may need to be supported in
591             UnifiedTransparencePrimitive2D, too, when interpreted as normally filled PolyPolygon.
592 			Implemented for:
593 				PRIMITIVE2D_ID_POLYPOLYGONGRAPHICPRIMITIVE2D,
594 				PRIMITIVE2D_ID_POLYPOLYGONHATCHPRIMITIVE2D,
595 				PRIMITIVE2D_ID_POLYPOLYGONGRADIENTPRIMITIVE2D,
596 				PRIMITIVE2D_ID_POLYPOLYGONCOLORPRIMITIVE2D,
597 				and for PRIMITIVE2D_ID_UNIFIEDTRANSPARENCEPRIMITIVE2D when detected unified transparence
598 
599             XPATHSTROKE_SEQ_BEGIN, XPATHSTROKE_SEQ_END:
600 
601 			Similar to pathfill, but using SvtGraphicStroke instead. It also has two producers where one
602 			is also the GDIMetaFile::Rotate. Another user is MetaCommentAction::Move which modifies the
603 			contained path accordingly.
604 			The other one is SdrObject::Imp_DrawLineGeometry. It's done when MetaFile is set at OutDev and
605 			only when geometry is a single polygon (!). I see no reason for that; in the PS exporter this
606 			would hinder to make use of PolyPolygon strokes. I will need to add support at:
607 				PRIMITIVE2D_ID_POLYGONHAIRLINEPRIMITIVE2D
608 				PRIMITIVE2D_ID_POLYGONSTROKEPRIMITIVE2D
609 				PRIMITIVE2D_ID_POLYGONSTROKEARROWPRIMITIVE2D
610 			This can be done hierarchical, too.
611 			Okay, base implementation done based on those three primitives.
612 
613             FIELD_SEQ_BEGIN, FIELD_SEQ_END
614 
615             Used from slideshow for URLs, created from diverse SvxField implementations inside
616             createBeginComment()/createEndComment(). createBeginComment() is used from editeng\impedit3.cxx
617             inside ImpEditEngine::Paint.
618             Created TextHierarchyFieldPrimitive2D and added needed infos there; it is an group primitive and wraps
619             text primitives (but is not limited to that). It contains the field type if special actions for the
620 			support of FIELD_SEQ_BEGIN/END are needed; this is the case for Page and URL fields. If more is
621 			needed, it may be supported there.
622             FIELD_SEQ_BEGIN;PageField
623             FIELD_SEQ_END
624             Okay, these are now completely supported by TextHierarchyFieldPrimitive2D. URL works, too.
625 
626             XTEXT
627 
628             XTEXT_EOC(i) end of character
629             XTEXT_EOW(i) end of word
630             XTEXT_EOS(i) end of sentence
631 
632             this three are with index and are created with the help of a i18n::XBreakIterator in
633             ImplDrawWithComments. Simplifying, moving out text painting, reworking to create some
634             data structure for holding those TEXT infos.
635             Supported directly by TextSimplePortionPrimitive2D with adding a Locale to the basic text
636             primitive. In the MetaFileRenderer, the creation is now done (see below). This has the advantage
637             that this creations do not need to be done for all paints all the time. This would be
638             expensive since the BreakIterator and it's usage is expensive and for each paint also the
639             whole character stops would need to be created.
640             Created only for TextDecoratedPortionPrimitive2D due to XTEXT_EOL and XTEXT_EOP (see below)
641 
642             XTEXT_EOL() end of line
643             XTEXT_EOP() end of paragraph
644 
645             First try with boolean marks at TextDecoratedPortionPrimitive2D did not work too well,
646 			i decided to solve it with structure. I added the TextHierarchyPrimitives for this,
647 			namely:
648 			- TextHierarchyLinePrimitive2D: Encapsulates single line
649 			- TextHierarchyParagraphPrimitive2D: Encapsulates single paragraph
650 			- TextHierarchyBlockPrimitive2D: encapsulates object texts (only one ATM)
651 			Those are now supported in hierarchy. This means the MetaFile renderer will support them
652 			by using them, reculrively using their content and adding MetaFile comments as needed.
653 			This also means that when another text layouter will be used it will be necessary to
654 			create/support the same HierarchyPrimitives to support users.
655 			To transport the information using this hierarchy is best suited to all future needs;
656 			the slideshow will be able to profit from it directly when using primitives; all other
657 			renderers not interested in the text structure will just ignore the encapsulations.
658 
659             XTEXT_PAINTSHAPE_BEGIN, XTEXT_PAINTSHAPE_END
660 			Supported now by the TextHierarchyBlockPrimitive2D.
661 
662             EPSReplacementGraphic:
663 			Only used in goodies\source\filter.vcl\ieps\ieps.cxx and svx\source\xml\xmlgrhlp.cxx to
664 			hold the original EPS which was imported in the same MetaFile as first 2 entries. Only
665 			used to export the original again (if exists).
666 			Not necessary to support with MetaFuleRenderer.
667 
668             XTEXT_SCROLLRECT, XTEXT_PAINTRECT
669 			Currently used to get extra MetaFile infos using GraphicExporter which again uses
670 			SdrTextObj::GetTextScrollMetaFileAndRectangle(). ATM works with primitives since
671 			the rectangle data is added directly by the GraphicsExporter as comment. Does not need
672 			to be adapted at once.
673 			When adapting later, the only user - the diashow - should directly use the provided
674 			Anination infos in the appropriate primitives (e.g. AnimatedSwitchPrimitive2D)
675 
676             PRNSPOOL_TRANSPARENTBITMAP_BEGIN, PRNSPOOL_TRANSPARENTBITMAP_END
677 			VCL usage when printing PL -> THB. Okay, THB confirms that it is only used as
678 			a fix (hack) while VCL printing. It is needed to not downscale a bitmap which
679 			was explicitely created for the printer already again to some default maximum
680 			bitmap sizes.
681 			Nothing to do here for the primitive renderer.
682 
683 			Support for vcl::PDFExtOutDevData:
684 			PL knows that SJ did that stuff, it's used to hold a pointer to PDFExtOutDevData at
685 			the OutDev. When set, some extra data is written there. Trying simple PDF export and
686 			watching if i get those infos.
687 			Well, a PDF export does not use e.g. ImpEditEngine::Paint since the PdfFilter uses
688 			the SdXImpressDocument::render and thus uses the VclMetafileProcessor2D. I will check
689 			if i get a PDFExtOutDevData at the target output device.
690 			Indeed, i get one. Checking what all may be done when that extra-device-info is there.
691 
692 		    All in all i have to talk to SJ. I will need to emulate some of those actions, but
693 			i need to discuss which ones.
694 			In the future, all those infos would be taken from the primitive sequence anyways,
695 			thus these extensions would potentially be temporary, too.
696             Discussed with SJ, added the necessary support and tested it. Details follow.
697 
698 			- In ImpEditEngine::Paint, paragraph infos and URL stuff is added.
699 			  Added in primitive MetaFile renderer.
700 			  Checking URL: Indeed, current version exports it, but it is missing in primitive
701 			  CWS version. Adding support.
702 			  Okay, URLs work. Checked, Done.
703 
704             - UnoControlPDFExportContact is only created when PDFExtOutDevData is used at the
705 			  target and uno control data is created in UnoControlPDFExportContact::do_PaintObject.
706 			  This may be added in primitive MetaFile renderer.
707 			  Adding support...
708 			  OOps, the necessary helper stuff is in svx/source/form/formpdxexport.cxx in namespace
709 			  svxform. Have to talk to FS if this has to be like that. Especially since
710 			  ::vcl::PDFWriter::AnyWidget is filled out, which is already part of vcl.
711 			  Wrote an eMail to FS, he is on vacation currently. I see no reason why not to move
712 			  that stuff to somewhere else, maybe tools or svtools ?!? We will see...
713               Moved to toolkit, so i have to link against it. I tried VCL first, but it did
714               not work since VCLUnoHelper::CreateFont is unresolved in VCL (!). Other then the name
715               may imply, it is defined in toolkit (!). Since toolkit is linked against VCL itself,
716               the lowest move,ment plave is toolkit.
717               Checked form control export, it works well. Done.
718 
719 		    - In goodies, in GraphicObject::Draw, when the used Graphic is linked, infos are
720 			  generated. I will need to check what happens here with primitives.
721 			  To support, use of GraphicPrimitive2D (PRIMITIVE2D_ID_GRAPHICPRIMITIVE2D) may be needed.
722 			  Added support, but feature is broken in main version, so i cannot test at all.
723 			  Writing a bug to CL (or SJ) and seeing what happens (#i80380#).
724               SJ took a look and we got it working. Tested VCL MetaFile Renderer based export,
725               as intended, the original file is exported. Works, Done.
726 
727 
728 
729 
730             To be done:
731 
732             - Maybe there are more places to take care of for vcl::PDFExtOutDevData!
