I have updated TODO list by difficulty order.

I will do Charcoal, Unsharp and Noise Reduction.

About SuperImpose, the plugin widget must be fixed accordinly with Achim B.K.O 
files. There is no backport. It's pure Qt widget implementation to do using 
QPixmap.

About Perspective, the algorithm must be ported to 16 bits. there is no 
backport to do.

Yes, especially about render algorithm. Widget rendering don't need to support 
16 bits mode. There is just an interface to do. Take a look in already ported 
plugin like refocus for example.

DigikamImagePlugins::ImageGuideDialog and DigikamImagePlugins::CtrlPanelDialog  
are obsolete now. dialog from digiKam core must be used instead.

In the same time, Digikam::DImgImageFilters must be used instead 
Digikam::ImageFilters. For example, Blur algorithm is used in any 
DigikamimagePlugins tools like Infrared. This is want mean that 
digikam/libs/filters will be removed before to release 0.9.0.

About changes in the UI code, I can do it in a plugins to give an example. I 
can prepare 'Add Border' tool or Blur FX' to about this point if you want.

About 'Add Border' tool, i have forget to said that we need to fix algorithm 
to preserve original image aspect ratio when a border is add to image (I have 
any requests from users about this point).
