Surface LIC: dashboard clean up and bug fix

cleanup dashboard warnings, make sure examples build, and also
renamed examples to match new module. fixed bug where invalid
extent was used when aabb points are behind near clip plane.
For in-place compositor make decomposition locally disjoint
to avoid redundant computations. Fixed unbalanced timer calls
added metrics for comparing domain decomp efficiecny and reporting
number of guard pixels used.
