44    PetscDrawRegisterDynamic - Adds a method to the graphics package.
45 
46    Synopsis:
47    #include "petscdraw.h"
48    PetscErrorCode PetscDrawRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(PetscDraw))
49 
50    Not Collective
51 
52    Input Parameters:
53 +  name_solver - name of a new user-defined solver
54 .  path - path (either absolute or relative) the library containing this solver
55 .  name_create - name of routine to create method context
56 -  routine_create - routine to create method context
57 
58    Level: developer
59 
60    Notes:
61    PetscDrawRegisterDynamic() may be called multiple times to add several user-defined solvers.
62 
63    If dynamic libraries are used, then the fourth input argument (routine_create)
64    is ignored.
65 
66    Sample usage:
67 .vb
68    PetscDrawRegisterDynamic("my_draw_type",/home/username/my_lib/lib/libO/solaris/mylib.a,
69                "MyDrawCreate",MyDrawCreate);
70 .ve
71 
72    Then, your solver can be chosen with the procedural interface via
73 $     PetscDrawSetType(ksp,"my_draw_type")
74    or at runtime via the option
75 $     -draw_type my_draw_type
