Now that the code is in C++, quite some duplication between "byte" and "float" effect code paths can be reduced (easier than it was in C times). So I did that, removing about 400 lines of code. In that process I accidentally made Gaussian Blur faster, since while reducing the amount of code I noticed it was doing some things sub-optimally (calculated kernel tables for each job, etc.). Applying 100x100 gaussian blur on 4K UHD resolution image strip on Ryzen 5950X went 630ms -> 450ms. Pull Request: https://projects.blender.org/blender/blender/pulls/116089
