'bg' parameter is not respected during plot creation #31

The following code demonstrates the bug:

tikz("try.tex", standAlone=TRUE)
 op<-par(bg=11,bty="n", cex=2, mar=c(3,4,1,2)+0.1)
 x <- runif(100)
 plot(x, las=1, yaxt="n",tcl=0, ann=F, type="l", lwd=2, col="blue")
 grid(col="white", lty="solid", nx=NA, ny=NULL, lwd=2)
 lines(x, col="blue", lwd=2)
 axis(1, tcl=0, labels=FALSE, col="black", lwd=1, at=as.Date(c("1970-01-01","2011-01-01")))
 axis(2, las=2, tick=FALSE)
 par(op)
dev.off()

There should be a green background but it is white. In addition, changing the tikz 'bg' parameter actually has no effect, it is never actually used in the code.

Looks like 2 things need to happen:

TikZ_Open and TikZ_NewPage need to call SetFill and SetAlpha to set a fill color and use \fill instead of \draw.
The drawing of the background needs to be delayed until the first call to a plotting function is made---that way the user has time to adjust the background using par after calling tikz.

It's fixed!
