When FLTK is enabled for Pango, the bounding width of strings is not correctly calculated for FLTK's internal fonts, when used as BOLD and/or ITALIC variant. This can be seen with unittests: Just change in unittest_text.cxx the first fl_font(FL_HELVETICA, 30) to fl_font(FL_HELVETICA_ITALIC) and (for better visibilty) add a character '/' to the end of the string. The proof that only FLTK's internal fonts are affected: When mapping the FL_HELVETICA font to e.g. "IArial" then the result is correct.
