409:    Synopsis:
410: #include <petscdraw.h>
411:     PetscErrorCode PetscDrawCollectiveEnd(PetscDraw draw)

413:    Collective

415:    Input Parameter:
416: .   draw - the draw object

418:    Level: advanced

420:    Notes:
421:    This is a macro that handles its own error checking, it does not return an error code.

423:    X windows draw operations that are enclosed by these routines handle correctly resizing or closing of
424:    the window without crashing the program.

426:    Developer Note:
427:    This only applies to X windows and so should have a more specific name such as `PetscDrawXCollectiveEnd()`

429: .seealso: `PetscDraw`, `PetscDrawCollectiveBegin()`
