Commit b71d9a6d15 (do not apply line dashing
in drawinglayer (tdf#136957), 2021-04-29) made sure that metafiles pass
dashing information in LineInfo of MetaPolyLineAction, instead of altering
the polyline itself. Since SVG export ignored dashing information in
MetaPolyLineAction, the exported lines were solid since that patch.
This patch introduces respective export support, emitting stroke-dasharray
attribute. As far as I see, it has exactly the same semantics, and renders
correctly in chrome and firefox. It also imports OK into Draw.

LibreOffice Filters
Filter registration and some simple filters (also descriptions).
Desperate splitting of code into small shared libraries for historical
reasons presumably (OS/2 and Windows 3.x). The libraries produced from
the code in each subdirectory of filter/source/graphicfilter are
graphic format import or export filters. But they don't have uniform
API. Some have either a GraphicImport or GraphicExport entry point,
and are loaded and used in a uniform fashion from code in
svtools/source/filter/filter.cxx. Others have different API and are
loaded from other places. For instance icgm has ImportCGM, and is
loaded and used by sd/source/filter/cgm/sdcgmfilter.cxx (!).
Svgreader is used for "File -> Open" and then to choose the svg file.
For "Insert -> Picture -> From File", see svgio/source/svgreader directory.
Filter Configuration
The filter configuration consists of two parts, the type definition in
filter/source/config/fragments/types/ and the actual filter definition
in filter/source/config/fragments/filters/.
Each file type e.g. text file should be represented by exactly one type definition. This type can then be referenced by several different filters, e.g. calc text, writer text.
