/**

* Can display bitmap with rounded corners. This implementation works only with ImageViews wrapped
|

* in ImageViewAware.
|
|
* <br />
|
|
* This implementation is inspired by
|
|
* <a href="http://www.curious-creature.org/2012/12/11/android-recipe-1-image-with-rounded-corners/">
|
|
* Romain Guy's article</a>. It rounds images using custom drawable drawing. Original bitmap isn't changed.

* If this implementation doesn't meet your needs then consider
|
|
* <a href="https://github.com/vinc3m1/RoundedImageView">RoundedImageView</a> or
|
|
* <a href="https://github.com/Pkmmte/CircularImageView">CircularImageView</a> projects for usage.
