Comment(by jorgearevalo):

 Ok, no problem with that. But what are the benefits of having a struct to
 keep pointers to functions against using variables, like done in PostGIS?

 Now, all raster core functions receive a pointer to rt_context object
 (static or dinamically allocated in rt_pg functions, it doesn't matter).
 In liblwgeom all functions use lwalloc, that simply calls the function
 pointed by lwalloc_var, declared in liblwgeom.h and set in the caller
 functions (the functions in postgis directory). Do you think the raster
 approach is better?
