(XftFont, XftDraw, XftColor, XGlyphInfo) [USE_CAIRO]: New typedefs.
(XftFontOpenName, XftFontClose, XftDrawCreate, XftDrawDestroy)
(XftDrawRect, XftDrawStringUtf8, XftTextExtentsUtf8) [USE_CAIRO]: New macros.
(crxft_font_open_name, crxft_font_close, crxft_draw_create)
(crxft_draw_rect, crxft_draw_string, crxft_text_extents) [USE_CAIRO]: New
externs.
* lwlib/lwlib-utils.c [USE_CAIRO]: Include math.h, cairo-ft.h, and
cairo-xlib.h.

cairo_surface_mark_dirty and cairo_surface_flush.
* lwlib/lwlib-Xaw.c [USE_CAIRO]: Include stdlib.h and lwlib-utils.h.
(draw_text) [USE_CAIRO]: Call cairo_surface_flush.
* src/xsettings.c [USE_CAIRO]: Include fontconfig.h
(apply_xft_settings) [!HAVE_XFT]: Don't call XftDefaultSubstitute or
XftDefaultSet.
