Added rt_ebm_centroid to src/librt/primitives/ebm/ebm.c and its declaration to src/librt/primitives/table.c
Michael, it's taken a while to process this patch due to a major release we've been working on since GCI, but your patch for ebm centroids has finally been integrated into BRL-CAD! It was included in commit r56092, thank you.
There were only a couple minor issues with the patch that needed to be corrected (*cent pointer gets the result and ws style issues), but it looked good. Centroid support is now enabled too, so your results will be user visible if you want to try it out.
Your name has been credited in our public release notes and will announced during the BRL-CAD 7.24.2+ release. Thank you again for the patch and hope you consider doing more work to improve BRL-CAD! We can certainly use people like you.
