screen mapped textures

[super gnu]

i spent all evening getting a wireframe shader working in gpu only to find that the screen-mapped texture i have to lay over it, doesnt work.

this is a massive show stopper for a project that in all other respects is ideal for gpu.

can anyone suggest a way to get screen-mapping, or an equivalent working on gpu?

solution: camera map per pixel

its not ideal as i have to remeber to assign the correct camera to it for each shot before rendering, but its better than nothing.
