Broken Basemap rotpole projection

Bug report

Bug summary

Basemap can't plot rotated-pole maps that cross rotated-grid's 0-th meridian

Code for reproduction
Here is a simple code that produce two maps for non-rotated grid (zero-rotation).
One does not cross Greenwich meridian another one does.

import matplotlib as mpl
mpl.use('AGG')

import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits.basemap import Basemap
import os

figname="okay.png"
fig = plt.figure()
bmap = Basemap(projection='rotpole',
       llcrnrx=0, urcrnry=15,
       urcrnrx=25, llcrnry=-15,
       lon_0 = 0,
       o_lon_p = 0.,
       o_lat_p = 90.,
       resolution='c')

bmap.drawmapboundary(fill_color='aqua')
bmap.fillcontinents(color='coral',lake_color='aqua')
bmap.drawcoastlines(linewidth=0.5)
bmap.drawparallels(np.arange(-20,20,10.))
bmap.drawmeridians(np.arange(-40,40,10.))

mpl.pyplot.savefig(figname)


figname="broken.png"
fig.clf()



bmap = Basemap(projection='rotpole',
       llcrnrx=-25, urcrnry=15,
       urcrnrx=25, llcrnry=-15,
       lon_0 = 0,
       o_lon_p = 0.,
       o_lat_p = 90.,
       resolution='c')

bmap.drawmapboundary(fill_color='aqua')
bmap.fillcontinents(color='coral',lake_color='aqua')
bmap.drawcoastlines(linewidth=0.5)
bmap.drawparallels(np.arange(-20,20,10.))
bmap.drawmeridians(np.arange(-40,40,10.))

mpl.pyplot.savefig(figname)

Actual outcome
Here are two maps.. The second one is obviously broken.

Matplotlib version

• Operating system: Python 2.7.1, python-matplotlib 1.5.1-1ubuntu1

Default Ubuntu 16.04.3 LTS installation

Commencez par exécuter le script de reproduction fourni et par comparer les deux cartes générées. Suivez la gestion par Basemap de la projection rotpole pour les limites qui traversent le méridien zéro de la grille tournée ; le travail est terminé lorsque les deux cas affichent correctement les limites de la carte, les côtes, les continents, les parallèles et les méridiens.
