Summary of feature description

iil4mitk has already been updated to support RGBA-images. mitk::ImageMapper2D only doesn't use it yet.

Proposed solution

mitk::ImageMapper2D requires a minor modification to select the new RGBA iil4mitk format.

mitk::PixelType needs also to be minor modified to support the itk::RGBAPixel<unsigned char> format.

Affected classes

mitk::ImageMapper2D

How will the bugfix get tested?

there are currently no tests for the imagemapper2D to extend. so we can currently only manual test it. a mapper testing framework is required.
