Hi, I have seen the comparison between the old (from gimp 2.8) and the new gaussian blur. I did not have a look at 2.8's implementation yet, but one of the main difference, is that the new implementation works in scRGB instead of sRGB in GIMP 2.8.
I don't know if you were aware about that. I personally would still let the possibility to make it work in both sRGB and scRGB, depending on user's need. Both behavior are useful. But it's still under discussion. I completely forgot that until now, but Massimo worked on Gaussian-Blur some times ago, and his work is now in operations/workshop (you have to pass --enable-workshop to autogen to build them). This implementation should replace the current implementation at some point, but the behavior is equivalent to the current implementation. I mean all the work you did still applies on the new implementation. The main thing that prevents the replacement is that the case with std-dev < 0.5 is not implemented. Among all improvements: Waaay faster, even with very large std-dev, it allows setting how edges are handled and finally it fixes the "vertical streaks" bug you were seeing with large std-dev. I don't answer to the rest because I don't know or I did not though about it yet. Though, we will need to find the equivalent conversion between the 2.8 gblur and GEGL, because 2.10 keeps api compatibility with 2.8 and that includes that all filters should be have the same given the same set of input parameter from the api point of view (that is, not necesserly in the ui).
