I hope someone may find this useful.
I design some objects that need to match drawings and screen grabs, so
I've been using a Windows utility to let me make the OpenSCAD GUI
transparent so I can compare my 3D object with the reference material.
Here is the utility.

I make the material full screen in my picture viewer, give focus to
OpenSCAD, and then set varying degrees of transparency while using an
external editor to update the SCAD files (dual monitors essential!). To
match each picture I have a "View" defined and use this include file to
let me set the camera based on whatever View is defined/overridden to be.
// Include into any file and set View to force certain camera settings
as per table below.
// View of empty string leaves camera unchanged.
View = "";
Views = [ // Name Rotate Translate Distance
[ "", [ $vpr, $vpt, $vpd ]],
[ "TopTail1", [ [0,0,90], [240, 0, 0], 540 ]], // ?
[ "TopTail2", [ [-20,0,86.7], [204, -12, 0], 780
]], // Angle to match overhead grab
[ "Side1", [ [90, 0, 0], [173, -12, 113],745 ]], //
Matches full screen b/w blueprint side view
[ "Top1", [ [0, 0, 0], [170, -41, 113],745 ]], //
Matches full screen b/w blueprint top view
[ "Landing1", [ [95.5, 1.5, 293], [154, 10, 5], 488
]], // Landing on elevator cars
[ "Side2", [ [90, 0, 0], [166, -12, 20], 880 ]],
// Side view in "clave" picture
[ "Side3", [ [90, 0, 5], [242, -12, 17], 530 ]]
// Side view of tail on runway
];
Result = search ([View], Views);
Index = Result[0]; // Search returns a vector
assert (len(Index) == undef); // View not found if not simple number.
Item = Views[Index][1];
$vpr = Item[0];
$vpt = Item[1];
$vpd = Item[2];
