* GraphicsImageXPM.[Ch]: more rigorous use of types (signed/unsigned).
(Data d-tor): introduce memory leak temporarily, to "fix" a crash in free_color_table. (unique_color_string): use the correct string c-tor. Could a gcc user post me any remaining warning messages? Angus git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@3594 a592a061-630c-0410-9148-cb99ea01b6c8
