The level-window is bounded by the minimum and maximum values of the image. This blocks certain level-window settings the user/radiologist might want or might be used to.
Thus, the range of the level window should not be limited to the range of the image voxels, but should extend the range if the user tries to enlarge the sliding-window by mouse interaction.
After exceeding the upper bound of the window while changing the level-window with pressed mouse and move the interaction isn't working.

Enlarged default range which is set according to the loaded image. Now the range of the default level window scale will be a little bit bigger than the defaul level window. This is done because the changes for T8690. Now if the user interacts with the levelwindow the levelwindow scale is no longer limited to the image histogramm but increases according to the user settings. Increasing the scale range by default prohibits a change of the scale size right with the first user interaction.

Removed check for valid level and window. This forced the window to remain within the default range which is given by the image independent from user interaction

COMP Fixed too late max/min range comparison for autoexpand = true and fixed mitkLevelWindowTest
