Make the rendering of the stroke outline *almost* transparent when in preview mode.
If you try to make it fully transparent then you will find that it is fully opauqe instead.
So it is now at 1/255 = 0.4% opaque, which I can't see when rendered even if the colors
are bright green or red.

Reveal partially hidden button in "FontInfo / Layers"

On both Ubuntu and Cygwin, when the "Layers" pane of the "Font Info..."
dialog was displayied, the "Delete" button below the "Layers:" list box
was obscured or hidden.

Upon first seeing this, the thought was that the entire "Font Info..."
dialog window would have to be made taller to display the button.
(Another pane "Lookups" would also seem to need this)

Instead, this fix merely shortens the list box, allowing the button to
rise and be seen.  This still allows as many as 8 layer descriptions
to be displayed without scrolling.
1327 version 1. This ports the API over to zeromq 4.0.4 and czmq 2.2.0.

changed in the most recent version.
