Do we really need the freetype2 dependency?

[FvD]

Just to minimize the amount of dependencies of the package: what are we using freetype2 for, because it requires a system-level install of libfontconfig1-dev

No package 'freetype2' found
Using PKG_CFLAGS=
Using PKG_LIBS=-lfontconfig -lfreetype
--------------------------- [ANTICONF] --------------------------------
Configuration failed to find the fontconfig freetype2 library. Try installing:
 * deb: libfontconfig1-dev (Debian, Ubuntu, etc)
 * rpm: fontconfig-devel (Fedora, EPEL)
 * csw: fontconfig_dev (Solaris)
 * brew: freetype (OSX)
If fontconfig freetype2 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a fontconfig freetype2.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
