   PetscDrawRegisterDynamic - Adds a method to the Krylov subspace solver package.

   Synopsis:
   int PetscDrawRegisterDynamic(char *name_solver,char *path,char *name_create,int (*routine_create)(PetscDraw))

   Not Collective

   Input Parameters:
+  name_solver - name of a new user-defined solver
.  path - path (either absolute or relative) the library containing this solver
.  name_create - name of routine to create method context
-  routine_create - routine to create method context

   Level: developer

   Notes:
   PetscDrawRegisterDynamic() may be called multiple times to add several user-defined solvers.

   If dynamic libraries are used, then the fourth input argument (routine_create)
   is ignored.

   Sample usage:
.vb
   PetscDrawRegisterDynamic("my_draw_type",/home/username/my_lib/lib/libO/solaris/mylib.a,
               "MyDrawCreate",MyDrawCreate);
.ve

   Then, your solver can be chosen with the procedural interface via
$     PetscDrawSetType(ksp,"my_draw_type")
   or at runtime via the option
$     -draw_type my_draw_type
