In Matplotlib 2.0.0, this produces a blank plot.\r\n\r\n**Code for reproduction**\r\n\r\nHere is an example that worked in 1.5.3.\r\n\r\n```python\r\nfrom matplotlib import pyplot as plt\r\nimport numpy as np\r\n\r\nlon = np.linspace(-np.pi, np.pi)\r\nlat = np.linspace(-np.pi/2, np.pi/2)\r\nlon, lat = np.meshgrid(lon, lat)\r\n\r\nax = plt.axes(projection='mollweide')\r\nax.grid()\r\nax.imshow(lon, extent=[-np.pi, np.pi, -np.pi/2, np.pi/2], aspect=ax.get_aspect())\r\nplt.savefig('test.png')\r\n```\r\n\r\n**Actual outcome**\r\n\r\nThis is the output on Matplotlib 2.0.0: blank axes.\r\n![test-2 0 0](https://cloud.githubusercontent.com/assets/728407/22172767/f2348f18-df7d-11e6-9f6d-0f15a1ca1d75.png)\r\n\r\n**Expected outcome**\r\n\r\nThis was the output in Matplotlib 1.5.3.\r\n![test-1 5 3](https://cloud.githubusercontent.com/assets/728407/22172765/eb9b1f28-df7d-11e6-90e0-90c6098b04e1.png)\r\n\r\n**Matplotlib version**\r\n\r\nInstalled from MacPorts on OS X 10.11.6 \"El Capitan\".
