File pycairo-1.10.0-80_fix-pickle.patch of Package python3-cairo

Description: During the build process, a Context instance is pickled, or at
 least attempted to be.  This fails because self.node_class is assigned to a
 class which is nested inside the __init__() method.  Because Python cannot
 find this class at unpickling time (i.e. it cannot be imported), Python
 refuses to pickle the Context instance, leading to a FTBFS.  Since there's no
 obvious reason why the class has to be so nested, moving it to a module
 global solves the build failure.
