grid line colors in republisher need to be changeable

[John Thomas Gill]

Scribe3 Chapel Hill- In republisher the grid lines in the crop box are blue. If the background of a book is blue, or really any dark color, the grid lines disappear and precision cropping is almost impossible. This is especially important in overcropping books, which here at UNC we are increasingly doing. It is really hard to overcrop a dark book with the dark grid lines in the crop box as a reference: they disappear. I would suggest a function like the Toggle opaque background, except toggle bright yellow grid lines, or in any case some color that isn't dark. There just needs to be two color options for the crop box lines.

A similar issue is that when one looks at the thumbnail image of the leaf one is on in republisher the thumbnail does not show the grid lines of the crop box on that leaf, it just shows the raw image. It would be helpful if that thumbnail also showed the crops. I have no idea if that is possible, but that would also help with the issue described above.
