pango/pangoft2.c (pango_ft2_render_layout) pango/pangowin32.c
2003-04-02 Sven Neumann <sven@gimp.org> * pango/pangoft2.c (pango_ft2_render_layout) * pango/pangowin32.c (pango_win32_render_layout) * pango/pangox.c (pango_x_render_layout): use a PangoLayoutIter to iterate over the lines and let render_layout_line() do the actual rendering. Fixes bug #105292.
