Annotation text bbox calculated incorrectly in matplotlib>=1.4.3? #4139
Description
Prior to matplotlib 1.4.3, text bounding boxes created with annotate did not include the connection arrow. Starting with 1.4.3 and continuing up to the current HEAD, the bbox includes the connection arrow.
As an example:
import matplotlib.pyplot as plt
import matplotlib
fig, ax = plt.subplots()
ax.annotate('Matplotlib {}'.format(matplotlib.__version__),
xy=(0.1, 0.1), xytext=(50, 50), size=20,
xycoords='data', textcoords='offset points',
bbox=dict(alpha=0.5, fc='yellow'),
arrowprops=dict(arrowstyle='->'))
plt.show()
