Surface.hasShowTextGlyphs

Returns whether the surface supports sophisticated cairo_show_text_glyphs() operations. That is, whether it actually uses the provided text and cluster data to a cairo_show_text_glyphs() call. Note: Even if this function returns FALSE, a cairo_show_text_glyphs() operation targeted at surface will still succeed. It just will act like a cairo_show_glyphs() operation. Users can use this function to avoid computing UTF-8 text and cluster mapping if the target surface does not use it. Since 1.8
