r-cran-freetypeharfbuzz 0.2.5+dfsg-2 (amd64 binary) in ubuntu focal

 Unlike other tools that dynamically link to the 'Cairo'
 stack, 'freetypeharfbuzz' is statically linked to specific
 versions of the 'FreeType' and 'harfbuzz' libraries (2.9 and 1.7.6
 respectively). This ensures deterministic computation of text box
 extents for situations where reproducible results are crucial (for
 instance unit tests of graphics).
