// Only pasteboard types mentioned here will be recognized, mapped, and available for pasting in a
// fresh LibreOffice process. When copy-pasting in-process, the situation is different.
// Also MIME types not mentioned here will be stored on the pasteboard (using the same type name),
// though. But that is IMHO a bit pointless as they in general won't then be pasteable anyway in a
// new LibreOffice process. See the use of the maOfficeOnlyTypes array.
// The SystemFlavor member is nil for the cases where there is no predefined pasteboard type UTI
// and we use the internal MIME type (media type) also on the pasteboard. That is OK in macOS,
// there is no requirement that the types are well-formed UTIs. It is different on iOS, I think,
// though. For an introduction to UTIs, see for instance
// https://alastairs-place.net/blog/2012/06/06/utis-are-better-than-you-think-and-heres-why/
//
// In those cases the MIME type might actually have parameters appended, separated by semicolons.
// At least the FLAVOR_SODX one must have at least a typename="%PRODUCTNAME %PRODUCTVERSION
// Spreadsheet" parameter (with macros expanded and translated) for LO to recognise it. See
// lcl_TestFormat() in sc/source/ui/view/cellsh.cxx.
