* src/pty.c(_vte_pty_set_utf8): toggle the IUTF8 flag, if it was defined at
	compile-time (maybe for #129317).
* src/vte.c(vte_terminal_set_encoding): call _vte_pty_set_utf8.
* src/vte.h (vte_terminal_anti_alias_get_type): declare.
* src/vtebg.c(vte_bg_get_pixmap): Optimisation to fix the ridiculous
	amount of time required to render solid colour or extremely small
	image tiled backgrounds.  This fixes bug #123903.  (desrt)
* src/vtebg.c(vte_bg_root_pixmap): move resize code into a separate
	function.
* src/vtebg.c(vte_bg_get_pixmap): Resize all image sources, in case
	we're using a very small image file for the background.
* python/Makefile.am: move python module to site-packages/gtk-2.0,
	which is added to the search path only by pygtk 2 (#92252).
