2x window resizing

Hi, first post here.

Is there an application that would allow me to resize any window, using a pixel perfect resizing, rather than just dragging a window by the corners? 

I know Winamp has a feature exactly like that, but I would like to do that to some other programs I have, like games for example.
I made an example image of what I want to do.
I want this because there are games or other programs that, upon resizing, use a pixel filter to soften pixels. I dont want that.

Thanks!
