commit b14583ba37 initially added the
parquet filter with saying
Note that this change makes it possible to load Apache Parquet files
if and only if orcus has been built with the parquet import filter
enabled. Using orcus without the parquet import filter enabled will
not break the build or run-time behavior; you just can't load parquet
files.
This is bad since silently failing like this doesn't tell people what
the problem is. Not having the option at all is clearer and more deterministic.
And the internal liborcus in a "standard" LibreOffice build didn't build with parquet
enabled at all anyway, thus leaving LibreOffice offering the option without even able to
load the files.
This patch adds
a) an explicit --with-parquet-filter configure flag on which the config
is built or not
b) based on that flag also gives --with-parquet-filter to liborcus'
configure. (which then of course will make that liborcus linked
against libparquet. But if people explicitely specify it..)
c) fixes the build of liborcus against arrow 23 (see
https://gitlab.com/orcus/orcus/-/commit/bae0e6e659cf4df2590288f566004eef7096dee4 -
that incidentially also fixed the liborcus build against 22 for me
This is a generalized version of a local patch I carry in Debian - which
I added some time after I made liborcus in Debian *do*
--with-parquet-filter :)

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.
