Expose vte_pty_set_size() and get_size() to localize terminal ioctl usage.vte_0_7_0
* src/pty.c, src/pty.h: Expose vte_pty_set_size() and get_size() to localize
terminal ioctl usage.
* src/ring.c(vte_ring_validate): Don't repeatedly compute the same value when
we know it won't change.
* src/vte.c(vte_wc_from_unichar): Implement for the non-STDC_ISO_10646 case,
heavily based on patch from Hidetoshi Tajima.
* src/vte.c(vte_terminal_ensure_cursor): Don't initialize the local data unless
we have to.
* src/vte.c(vte_terminal_process_incoming): Don't insert NUL characters into
the display, matching behavior of xterm.
* src/vte.c: Clean up use of various G_PRIORITY values throughout to allow for
simpler tuning. Rewrite rendering code to use per-paint PangoLayouts
when they're needed, use Xft2's DrawCharSpec function when available,
and to cut down on X requests. Don't paint on expose events if the
window isn't realized, drawable, and at least partially visible. Don't
deselect previous selection when the user clicks unless there's also a
drag first.
