Wrong result size for scaled image search #68

Version
1.1.2

Short overview
When a given input image is detected on a smaller scale, an unscaled target region is returned.

Detailed error description
When searching for a larger image on a screen, e.g. when using input images captured on retina displays on a regular display, the returned image region is unscaled.
This results in a larger result region, than the actual image on screen, which might cause clicks outside the target.

Steps to reproduce error
Use an input image e.g. twice the scale than on screen and try to locate it.
