adding better isViewInBounds check

[AhmedvHashem]

We salute you for this library, we are using it in our current project, it saved us a lot of time.

i added an extra functionality that was needed, and i think it should be default it the library

when you move the image/sticker/text vertically the isViewInBounds() works perfectly but when moving horizontally it does not cuz it fits the width of the screen to the touch position never exceed the bounds of the container view.

so i added that functinallity

@AhmedNTS Since you are using this in your project, I am considering this for my project, are there any bugs with this library?
