Polygons and tissot across the edge in Mollweide:

There seems to be a known problem with tissot and Polygon in the 'Mollweide' projection with basemap when these objects cross the 'limb' (180 degree line if the central longitude is 0. which is both the East and West edges of the map). The obvious solution is of course to split this into two polygons split at the limb. I realized that this was actually already available in examples (for tissots):
https://github.com/matplotlib/basemap/blob/master/examples/allskymap.py
and am wondering if there are plans to eventually replace Basemap.tissot or if there are deeper problems with this.

Commencez par le traitement de Basemap.tissot et de Polygon pour la projection de Mollweide, puis comparez l’approche existante liée à tissot dans examples/allskymap.py. Reproduisez le cas où un objet franchit le limbe et déterminez le comportement attendu ; l’issue ne définit pas de condition d’acceptation concrète au-delà de la résolution du problème de franchissement du bord.
