Summary: Double buffering doesn't work properly in new viewer

Initial Comment:
Double buffering doesn't seem to work properly with the FLTK viewer, nor the 
latest Java viewer in trunk (most likely because the Java viewer is borrowing 
the FLTK viewer's logic.)  The easiest way I've found to repro this is to run 
GLXspheres in VirtualGL and add 200 ms of artificial latency to the server:

sudo tc qdisc add dev eth0 root netem delay 200ms
vglrun /opt/VirtualGL/bin/glxspheres -i

Rotate the spheres, then stop, then start rotating them again.  You should 
observe "notches" disappear from the upper spheres, most likely due to some of 
the solid rectangles not being rendered prior to the frame advancing.  I also 
observe frequent tearing artifacts, whereby only half of the frame is drawn 
before it advances.

I observe this most readily on a RHEL 6 client (nVidia GeForce) connecting to a 
RHEL 5 server, but I also observe it to a lesser degree when using my Mac Mini 
as a client.
