Suggestion: Add Auto Zoom functionality when user resizes cropper

[DharmeshBasapatiBacancy]

Hi SmartToolFactory,

I know you are doing great work.

But could you guys please add auto-zoom functionality (where image scales to the region of the cropper automatically) to this library as this is the only thing I think is pending to make this library one of the best place for implementing Image Croppers in Android.

Hope you achieve this as soon as possible. Fingers crossed.

Thanks.
