I am not sure... With the debugHUD in the ShadowMap example, there was just
a window which appeared to display the shadow map in gray-scale, but in the
LISPSM example, there appears to be two sub-windows in the debughud window
(not in gray-scale). What are these displaying?

I found the shader source, in StandardShadowMap::StandardShadowMap. I am a
bit confused about how to use the osgShadow in my app if I already have
shaders in my app.
The osgShadow programmers guide says
" What if my objects already have a shader applied to them?
* That shader also needs to implement shadow mapping. See the top of
src/osgShadow/ShadowMap.cpp for the basic shader, and use that in your
shader (keep the same names for the variables too)."
Am I supposed to, basically, copy the shader code from StandardShader map
and add it to my shaders and turn off the LISPSM shaders?
