dnl  - Macro: CAIRO_BACKEND_ENABLE (NAMESPACE, NAME, ARG, FEATURE_NAME, DEFAULT, COMMANDS)
dnl
dnl where:
dnl
dnl	NAMESPACE is the sub-namespace in function names, eg. "ft" for cairo_ft_...
dnl	NAME is the human-readable name of the backend, eg. "FreeType font"
dnl	ARG is what enables the backend, eg. "freetype" for --enable-freetype
dnl	FEATURE_NAME is what's used in cairo-features.h, eg. FT_FONT for CAIRO_HAS_FT_FONT
dnl	DEFAULT is the default state of the backend:
dnl		"no" for experimental backends, eg. your favorite new backend
dnl		"yes" for mandatory backends, eg. png
dnl		"auto" for other supported backends, eg. xlib
dnl	COMMANDS are run to check whether the backend can be enabled.  Their
dnl		result may be cached, so user should not count on them being run.
dnl		They should set use_$(NAMESPACE) to something other than yes if the
dnl		backend cannot be built, eg. "no (requires SomeThing)".  It then
dnl		should also set $(NAMESPACE)_REQUIRES/CFLAGS/LIBS/...
dnl		appropriately.  Look at the macro definition for more details,
dnl		or ask if in doubt.
