Just discovered that the clipping in the new layer modes needs more work. It's not a problem with colors that originated in sRGB, but the layer modes can easily construct colors outside sRGB, or even invisible/virtual colors. The current behavior is different from floating point/GEGL implementation.
Especially when composing e.g. in Color mode onto a white layer, results differ. A red onto white will become yellow (which isn't necessarily worse than the red from floating point, as it seems to be closer to correct lightness -- but it's different.) The problem is that I have to clip twice in integer mode: once from Lab to XYZ, then again from XYZ to RGB. Widening the lab-to-xyz LUT solved the problem for red, but created strange color bandings for blue, so it probably leads to integer overflow somewhere. In other words: I'll have to work on the lab-to-rgb conversions...
