Here is a minor patch for the mplot3d.view_init() function. It:
1. comments this method so that users know that they can use it to
programatically rotate or re-set the axes.
2. adds some new functionality so that if no parameters are passed in, the
default values (what was specified in the Axes3D constructor) are used instead.
This diff was created with SVN head revision 8199.
I tested the new feature with my own code to verify it works, but don't have
any example code or test scripts to submit.
Thanks,
-Ben
