  Use Cairo XCB surfaces when XCB is available
  
  This lets us get at goodies such as shm support, which aren't
  available with the xlib surface.  (bug#52120)
  
  * configure.ac: Test for cairo-xcb if cairo is available on X.
  * src/xterm.c (USE_CAIRO_XCB_SURFACE): New define.
  (x_begin_cr_clip): Create XCB surfaces if available.
  (x_try_cr_xlib_drawable):
  (x_scroll_run): Handle XCB surfaces.
  (x_term_init): Find XCB visualtype structure.
  * src/xterm.h (struct x_display_info): New field `xcb_visual'.
  * src/xwidget.c (x_draw_xwidget_glyph_string): Fix integer
  overflow.
