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).
