--- part_changed(part)
- Informs Pango that the way that the renderering is done for part has changed in a way that would prevent multiple pieces being joined together into one drawing call. For instance, if a subclass of Pango::Renderer was to add a stipple option for drawing underlines, it needs to call Pango::Renderer#part_changed(Pango::Renderer::PART_UNDERLINE). When the stipple changes or underlines with different stipples might be joined together. Pango automatically calls this for changes to colors. (See Pango::Renderer#set_color)
