small bug when plotting empty images about antsr HOT 5 CLOSED

Ah, yes, that makes sense. It probably depends on how R computes quantiles
of a totally uniform distribution. We can correct this.

predlabel2 = predlabel*0
plot(predlabel2)
Error in if (window.img[1] == window.img[2]) window.img[1] <- min(x) :
missing value where TRUE/FALSE needed

Since we are here, you may want to add something that checks if image is a label image, like

length(labels(as.factor(as.array(img))))<10

and keep the window 0 to max.
Some labels don't appear with automatic windowing. Problem is that the code above is kind of slow.

We should have better support for labeling anyway. We currently assume the
overlay is basically continuous; if we deal with labels correctly, we
should have a specific list of colors, not a heatmap-type visualization.

Yeap, need to make 0 value transparent on overlay.

Also, alpha setting still doesn't work (compiled yesterday at 4pm).

Fixed this issue. As for the labels: Setting the window.overlay to the max and min values of the labels and setting the colorbar to "rainbow" should work pretty well.
