Do not slide in the full screen bar when dragging image
Review Request #102359 - Created Aug. 18, 2011 and discarded
People complain that when they scroll an image by dragging and move the mouse pointer to the top of the screen in full screen mode, the thumbnail bar appears and there is no way to hide it again unless you release the mouse button.

I could commit+push this, but writing here instead because I didn't try to compile Gwenview with this patch.
