annotate libinterp/corefcn/latex-text-renderer.cc @ 29483:af41ebf3d1b3

Differ latex test until actually needed (bug #59546) * base-text-renderer.h (ok): New virtuel method. * latex-text-renderer.cc (m_testing): New bool attribute to store wether the renderer still needs to be tested. (is_usable): Remove method. (ok): Reimplement method. (warn_helper): Now a member function with less arguments. Change use cases. Don't warn while testing unless debug is requested. (make_latex_text_renderer): Return an object without testing. * text-renderer.cc (latex_ok): Remove method. (set_color, set_font): Don't check the latex renderer is functionnal. (text_to_strlist,text_to_pixels, get_extent): Use the latex_renderer.ok () method to test when needed.
