As stated by Sandy in T15693:
The mitkImageVtkMapper2DLookupTableTest failes on the windows continuous. However, the test passes on local machines (Casper, Thomas, Sandy).
We tried to fix it by disabling the "texture interpolation" property (=false) in the test.
Unfortunaly this did not help to pass the test on the windows continuous virtual machine.
We assume the test image is not well chosen, because of the aliased font.
However, there is another test successfully using this image (mitkImageVtkMapper2DTransferFunctionTest), but with a error threshold. Potentially, it has the same problem as the mitkImageVtkMapper2DLookupTableTest.
Currently the test is not active. Todo: Reactivate and fix it.
