	* tools/pdbgen/lib.pl: use the variable initializer defined with
	the PDB type instead of figuring it manually. Removed a line of
	code that checked for enums without "Gimp" prefix.

	* libgimp/gimpbrush_pdb.c
	* libgimp/gimpchannel_pdb.c
	* libgimp/gimpcontext_pdb.c
	* libgimp/gimpgradient_pdb.c
	* libgimp/gimplayer_pdb.c
	* libgimp/gimpunit_pdb.c
	* libgimp/gimpvectors_pdb.c: all doubles are initialized with 0.0
	instead of 0 now.
