Jump to Offset not working for some values

[kainjow]

I have byte grouping set to 4, and if I jump to an offset that is the start of a row (e.g. 0, 16, 112, etc), I get an assert in updateSelectionPulse:461. In release mode that means the image has a height of 0 and then Cocoa throws an exception trying to lock focus on an invalid image size.

It seems e57b46e introduced the issue. @percontation what was that change for? The commit is vague. If I undo that commit, it works fine.

The mechanism to restore focus to the non-banner view wasn't being applied to this particular banner; this commit added that in.

Oh, and also, the selection pulse was modified to better reflect where activity was occurring. I guess that's the part that broke something.

Okay, I see the problem, I'll push a fix.
