The new features since PhotoController v2.1

The following bugs are fixed:

1. Feather.BuildCurveMask parameter fillmode and tension didn't work
2. Feather.LoadTileBitmap ( Bitmap ) didn't work
3. In SharpenFilter and MeanRemovalFilter, smaller level gave a sharper feeling, which didn't make sense.

The features are either brand new or being enhanced:

1. New added Filter classes:
   
   BombWaveFilter
   OilFilter
   RedEyeFilter
   SpreadFilter
   WindFilter
   AutoColorEnhanceFilter
   LinearBlurFilter
   ZoomBlurFilter
   RadialBlurFilter
   
   
2. Writing border to image is refactored.
   
   The previous struct Borders is removed. Instead, under IC.PhotoController.Border namespace, you have a new class BorderBuilder, a new enumeration BorderAlignment, and the namespace of BorderStyle is changed.
   
   Also, the previous method SetBorder parameter is changed to accept the BorderBuilder class.
   
   
3. A new property DrawArea is added to BaseFilter
   
   
4. A new event PercentageHandler is added to the IC.PhotoController.Filter namespace.
   
   This event is delegated to BaseFilter.PercentageChangedHandler, which is used to determine the processing status of a filter.
   
   At the same time, in BaseFilter, a new proptected method UpdatePercentage is added, which can be called to update the processing status from your customer filter. All built-in filters have already handled this. So from now on, you can keep your user posted when the filter is processing, i.e. update your progress bar.
   
   
5. In FeatherBuilder, a new property BackgroundBrush is added. And in FeatherBackgroundStyle, a new value UserBrush is added.
   
   Now, you can use a specified brush to draw the feather background.
   
   
6. BaseColorFilter uses a faster color assignment algorithm.
   
   
7. The document is enhanced a lot, including more details and examples are added to many classes.
   
   
8. The demo application is enhanced a lot, including restructure the code, change the selection algorithm, re-group the filter, rewrite the borders form, and so on.
   
   
9. More samples, including VB.NET source, are available to download from the website.

   Each filter is an independent class, which inherits from an abstract class BaseFilter

   The Filter class hierarchy will be as follows:
