But the specific patch mentioned doesn't directly do anything about glyphs. It only enables lcdfilter options if it's _already compiled_ into the system's FreeType libs; that is, any patent issue would lie not in cairo, but in the freetype binaries because the distribution or the user chose to enable patented features, so it shouldn't be a problem for Mozilla source to include that patch. Am I misunderstanding the situation here?
