When sending a "vis 1" to a GOP subpatch, it produces a "consistency
check failed: canvas_vis" though it seems to work fine. I am wondering
if this is still supposed to be true: x == glist_getcanvas(x). In
g_editor.c, canvas_vis() starts out with:
void canvas_vis(t_canvas *x, t_floatarg f)
{
char buf[30];
int flag = (f != 0);
if (x != glist_getcanvas(x))
bug("canvas_vis");
