It seems that the first image or two of a set are saved blank. I was
going to patch this bug, but my perl abilities are non-existent and
lmlib2 only has a pixel by pixel read function.
The plan was to make a while loop that would check the canvas data of
the image for a value other than zero (black). If it found something
other than black, we would assume there's an image worth keeping and
save that.
This inital blank screen a known problem with certain VNC servers
though. There's an older competing product that does the same here:
http://vncsnapshot.sourceforge.net/ they use a command-line switch
'-ignoreblank' to ensure they save something useful before moving on.
