This patch adds an inheritable option, “font-shaping”, that controls whether a particle that renders text should enable font-shaping or not. The option works similar to the ‘font’ option: one can set it at the top-level, and it gets inherited down through all modules and to their particles. Or, you can set it on a module and it gets inherited to all its particles, but not to other modules’ particles. Finally, you can set it on individual particles, in which case it only applies to them (or “child” particles). When font-shaping is enabled (the default), the string particle shapes full text runs using the fcft_rasterize_text_run_utf32() API. In fcft, this results in HarfBuzz being used to shape the string. When disabled, the string particle instead uses the simpler fcft_rasterize_char_utf32() API, which rasterizes individual characters. This gives user greater control over the font rendering. One example is bitmap fonts, which HarfBuzz often doesn’t get right. Closes #159
