Subpixel rendering in Fedora 22

I've spent last week trying to get subpixel rendering working with fedora's freetype package, and even though it had the patch...

   /* This is done to allow FreeType clients to run unmodified, forcing     */

   /*                                                                       */


... the fonts still looked horribly (e.g. this web page)

Today I actually read the spec file, and it started with...

# Patented subpixel rendering disabled by default.
# Pass '--with subpixel_rendering' on rpmbuild command-line to enable.
%{!?_with_subpixel_rendering: %{!?_without_subpixel_rendering: %define _without_subpixel_rendering --without-subpixel_rendering}}

insert a minute of swearing

Everybody seem to be all hyped about infinality patches, and they do make the fonts look great, but these were already merged.

rpmbuild  -bb freetype.spec --with subpixel_rendering

Even Cantarell font looks almost decent now.
