[Tikzdevice-bugs] Background color for tikzDevice

[Cameron Bracken]

Yihui-

We certainly intended it to but It does not right now. The bg and fg
arguments are are available but don't do anything.  We will have to
think a little about how to implement these correctly since they are
not very well defined.  For your particular example you can change the
line near the top from

\draw[color=white,opacity=0] (0,0) rectangle (505.89,505.89);

to

\filldraw[black] (0,0) rectangle (505.89,505.89);

Sorry that is a pain.  It should not be too hard to implement and we
can probably get it into the next release.
