Today Øyvind pointed out to me that he has always had a hard time
getting the right function from among the four choices of

	cairo_transform_point
	cairo_transform_distance
	cairo_inverse_transform_point
	cairo_inverse_transform_distance

So, we talked about replacements that would be more clear, (and on
almost all cases shorter), and came up with:

	cairo_user_to_device
	cairo_user_to_device_vector
	cairo_device_to_user
	cairo_device_to_user_vector

And changing this would free us up to rename cairo_concat_matrix to
cairo_transform as discussed above.
