Viewport breaks TextureButton

[stisa]

When I enable "stretch_aspect : viewport" in Project Settings, TextureButtons stop registering clicks, although they display correctly.
I think it's similar to this issue #10

I think I'm having the same issue. In my project settings, I've got stretch_mode=viewport and stretch_aspect=keep_height. This causes touch events to stop generating calls to _input. Seems reasonable to think that a lack of input events would explain the TextureButton being unresponsive.
