legend.m: Text objects should inherit textcolor, interpreter properties from legend (bug #40064). * scripts/plot/legend.m: Match variable names in function prototype to docstring. Get textcolor and interpreter properties from legend axis object and apply them when creating text objects. Use '~' to ignore dummy input to callback functions. Remove some for loops for performance.
