questions about the package

[Alex0573]

First, let me say - Thank you and a great job. An excellent package.

There are two questions I wanted to ask you:

1. When installing, you require the "viz" lib, but by the command you provided won't generate it. Have you been able to configure the default settings of OpenCV to compile that lib without extra SW?
   I had to get the VTK software, and compile OpenCV with reference to it.

2. When calling destroyWindow() or destroyAllWindows() - the images aren't being closed.
   It seems you need to add something like waitkey(1) after the call to the destructors in order to successfully close them.
   Have you encountered something similar?

Thanks
