Orange: ImageWindow goodies

- options to show with alpha-over (checkered backdrop), only alpha (BW) and
when available: the zbuffer.
Note: it's icons in the header, I just re-used existing ones, no time now
for fancy design. :)

Also: recoded the way alpha-only draws, also in renderwindow. Mucho faster!

Oh, and sampling the buffer with LMB now displays z values in float range
of 0.0 to 1.0. Note that we still save signed int in files for Z...
