To get better looking fonts with SlickEdit 12.0.3, I use the X11 release from
http://xquartz.macosforge.org/trac/ with a custom build of the freetype library that has the following configured inside include/freetype/config/ftoption.h:
Uncomment the following lines:
#define FT_CONFIG_OPTION_SUBPIXEL_RENDERING
#define TT_CONFIG_OPTION_BYTECODE_INTERPRETER
Comment the following line:
#define TT_CONFIG_OPTION_UNPATENTED_HINTING
The latest X11 release from XQuartz is 2.3.3. This new version includes freetype library version 2.3.9 (previous releases used freetype 2.3.7). The source for freetype 2.3.9 can be downloaded from
http://mirror.its.uidaho.edu/pub/savannah/freetype/Once X11 release 2.3.3 is installed, download freetype 2.3.9 and build it by running ./configure and then, make. Then, copy freetype-2.3.9/objs/.libs/libfreetype.6.dylib to the /usr/X11/lib directory (you may want to make a back up of /usr/X11/lib/libfreetype.6.dylib first).
