Hi Berk,<br>
<br>
Just checking in. I'm sure it's one of those things that could get
lost in the shuffle.<br>

Would anyone be willing to review this patch?<br>

I was profiling VisIt and noticed that
vtkDepthSortPolyData (in spite of its limitations it is
used by VisIt for transparent rendering) made use of qsort
and about 1/2 the time was spent by qsort. std::sort is
known to be faster because of the possibility of the
compiler to inline the comparisons. Updating qsort to
std::sort seemed like an easy way to make it faster. As I
worked the profiler pointed out a number of other fairly
easy things to improve and overall the class is now ~3x
faster for two of the modes and ~2x faster for the other.
I enumerated the changes in the commit message and have
added a cxx test to improve the test coverage.<br>
<br>
If you have the time, please take a look, and let me know
if you have any feedback on it.<br>
<br>
Thanks<br>
Burlen<br>
