Show dimensions text sprite issue

[EunBeen Kim]

When I checked Show Tensor Dimensions and Show Conv Dimensions in AlexNet style, the text sprite (width and height) is showing wrong place. The width and height texts seem to be exchanged each other in location.

Thanks for the issue. Can you check that #30 fixes this?

I commented your #30 :)
