Description
Bug summary
Calling add_lines on a horizontal colorbar is broken since commit 146856b
Code for reproduction
import matplotlib.pyplot as plt
from matplotlib import colorbar
fig, ax = plt.subplots()
CS = ax.contour([[0.0, 1.0, 0.0, 0.0], [0.0, 0.0, 1.0, 0.0]])
cb = colorbar.Colorbar(ax, CS, orientation='horizontal')
cb.add_lines(CS)Actual outcome
