Fix segfault when '[]' used for row_vector_property. * graphics.in.h (row_vector_property::add_constraint (octave_idx_type len)): Remove validation that accepts 0x0 matrix. * graphics.in.h (image::init): Call add_constraint() to allow 0x0 since xdata, ydata can legitimately be '[]' for these properties.
