#include <lqr.h>
The function init_func is of type LqrProgressFuncInit, whose prototype is defined by:
typedef LqrRetVal (*LqrProgressFuncInit) (const gchar* init_message);
Each time that the function lqr_carver_resize(3) performs a rescale operation (recall that it can perform more than one rescale operation at each call) this function will be called first, with a string argument passed through the parameter init_message, which is different for horizontal and vertical rescalings.
The message arguments can be set with the functions lqr_progress_set_init_width_message(3) and lqr_progress_set_init_height_message(3).
The default values for newly created LqrProgress objects are:
Horizontal:
"Resizing width..."
Vertical:
"Resizing height..."
The return value follows the Liquid Rescale library signalling system.
