NAME
lqr_carver_init - activates an LqrCarver object
SYNOPSIS
#include <lqr.h>
LqrRetVal lqr_carver_init(LqrCarver* carver, gint delta_x,
gfloat rigidity);
DESCRIPTION
The function lqr_carver_init initialises the LqrCarver pointed to by
carver, so that it can compute the visibility maps as needed upon calls
of lqr_carver_resize.
The parameter delta_x controls the maximum transversal step a seam can
make. A value of 0 means straight seams. Normally, it is set to 1.
The parameter rigidity can be used to add a negative bias to
non-straight seams, and it is normally set to 0.
Visibility maps must not be loaded with the function lqr_vmap_load when
using this function, neither before nor after invoking it.
RETURN VALUE
The return value follows the Liquid Rescale library signalling system.
