# System dependencies for the .NET runtime and cross-platform rendering:
#  - libicu-dev: .NET globalization (ICU)
#  - libgdiplus + libfontconfig1 + fontconfig: GDI+/font support used by
#    several rendering paths (PDF, presentations, Visio, CAD, eBooks)
#  - fonts-dejavu + fonts-liberation: real fonts so text renders; the
#    Liberation set is metric-compatible with Arial/Times/Courier.
# Without fonts, font-dependent rendering throws (e.g. "trueTypeFont" null
# or a font type-initializer exception).
