New description:
This bug tracks the current status of the toric varieties code and the
interdependence of new patches, which should be applied '''on top of Sage
5.2'''. Any (properly ordered) part of positively reviewed patches can be
merged at any time, there is no need to "bundle tickets."
'''Applied to the current Sage alpha/beta/rc:'''
'''Applied to the next alpha/beta/rc:'''
'''Positively reviewed:'''
'''Need work/review:'''
These groups (separated by blank lines) can be applied independently on
top of the positively reviewed ones:
* #11559: Speed up Posets and toric Chow group
* #13183: Implement index(cone) for fan morphisms
* #12892: Toric fibration morphisms
* #12900: (Demazure) roots of toric varieties
* #13189: fan isomorphism
* #11763: Parents for polyhedra
* #12553: Add interface for PALP polytope databases
* #13084: Weierstrass form for toric elliptic curves
* #13194: !FaceFan and !NormalFan should work with (non-lattice)
polyhedra
