Bug summary

The tight bounding box of a Wedge patch appears to be incorrect. I suspect this is HiDPI issue - multiplying x0/y0/width/height by 2 seems to result in the correct bounding box for me.

Code for reproduction

import matplotlib.pyplot as plt
from matplotlib.patches import Rectangle, Wedge

fig, ax = plt.subplots()
wedge = Wedge(0.5, 0.4, 10, 30)
ax.add_patch(wedge)

# Plot bounding box
renderer = fig.canvas.get_renderer()
bbox = wedge.get_tightbbox(renderer)
rect = Rectangle((bbox.x0, bbox.y0), width=bbox.width, height=bbox.height,
                 linewidth=72./fig.dpi, edgecolor="red", facecolor="none",
                 transform=None)
fig.add_artist(rect)
plt.show()

Actual outcome

Expected outcome

Red bounding box bounds the blue wedge.
