Issue the "instead of O[U]String, pass [u16]string_view" diagnostic also for operator call arguments. (The "rather than copy, pass subView()" diagnostic is already part of handleSubExprThatCouldBeView, so no need to repeat it explicitly for operator call arguments.) (And many call sites don't even require an explicit [u16]string_view, esp. with the recent ad48b2b02f83eed41fb1eb8d16de7e804156fcf1 "Optimized OString operator += overloads". Just some test code in sal/qa/ that explicitly tests the O[U]String functionality had to be excluded.)

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.
