Mike Kaganski a6a6921123 Use good old string literals in assertXPath and friends
These are only sent to an external API expecting char*-like strings,
or for comparison. Having every assertXPath having three of _[ou]str
is too much syntactic noise, making the unit tests almost unreadable.

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.
