Change some method names to comply with FLTK style as discussed in fltk.coredev, thread "Fl_Flex method name question". * Rename Fl_Flex::margins(...) to Fl_Flex::margin(...) (use singular form for all margin related methods) * Remove Fl_Flex::setSize() and isSetSize() "backwards compatibility" methods * Rename Fl_Flex::set_size(...) to fixed(...) Note: the latter affects existing (pre-release) fluid (.fl) files: you may want to edit and replace "set_size_tuples" with "fixed_size_tuples"
