              However, freetype scaler is basically small wrapper on
              top of freetype library (that is used in binary form).

              This wrapper is compiled into fontmanager and this make
              fontmanger library depending on freetype library.

              On Windows DLL's in the JRE's BIN directory cannot be
              found by windows DLL loading as that directory is not
              on the Windows PATH.

              To avoid link error we have to load freetype explicitly
              before we load fontmanager.

              NB: consider moving freetype wrapper part to separate
                  shared library in order to avoid dependency. */
