BUG: Fix GeodesicActiveContourImageFilterOutput7.png

This image was not correctly generated, resulting in an empty black image.

Change-Id: If60cf0c66d3adeb64710cf738b62cbf1e2bd09c9
STYLE: Threshold Segmentation LevelSet Image Filter Figure

Use a normal figure instead of a floating figure, which is messing up the layout.
(some code was displayed above the figure, and the caption was truncated).

BUG: GDCM does not apply rescale slope / intercept on write.

Make use of the InternalComponentType, which is the pixel type
before rescale slope/intercept have been applied when reading from disk.

This internal component and rescale slope from the reader can be used in
a writer for the DICOM image with

  dicomWriter->SetImageIO( readersGDCMImageIO );
  dicomWriter->UseInputMetaDataDictionaryOff();

Make sure the written DICOM images are verified against baselines in the
tests.
