A bug in mpl_toolkits.mplot3d.axes3d

[sprite728]

The original code contains self._draw_grid = maxes._string_to_bool(b), but the _string_to_bool is missing. However, it seems that b is already a boolean but not a string, I wonder why _string_to_bool is needed. After changing this line to self._draw_grid = b resolve the AttributeError issue.

Can you test this with 1.4.1rc1 ? I think this had been fixed.

I see, just update it to 1.5.x and the code is changed to "self._draw_grid = cbook._string_to_bool(b)", which fix the problem. Thanks.
