Title: Advanced UI Additions (Fields, Managers, Decor, and Example Implementations)

// Component
AutoScaleImageField.java – a field that will scale an image into a given space
SliderField.java – already existed, added some focus functionality

// Container
FieldSet.java – a manager with a special kind of border around it. Light weight, highly customizable

// Décor
BitmapBorderBackground.java – Shows how to create a custom Background.
BitmapMask.java – An illustration of how a developer can modify a bitmap image on BlackBerry one pixel at a time. This one is easily used to round corners of images, could be changed to implement filters.

// Images
All the images support the existing code, or the code included here.

// test
Any changes in these files are purely to illustrate the concepts above. They’re sample implementations.
