Raytraced: improve ViewCaptureTo* support.
Raytraced: improve ViewCaptureTo* support.

Explicitely adding a wireframe channel
to the RenderWindow causes unnecessary tiled
drawing setup for those. That setup step
messes up the copying of final result into
the clipboard.

The wireframe channel doesn't have to be added,
since the display mode conduit handles that already
for the user.
