Obviously it was my fault: I had not removed the clip in Blend Program....
I re-tested and most of the color-related plugins do not have
clipping. Unfortunately (at least for me) some of the most important
plugins have it:
Blur
Try to look for switch(color) in plugins/blur/blur.C
and replace for testing 1.0 for rgba/rgb float cases with FLT_MAX ? Like in our earlier work ....
case BC_RGBA_FLOAT: BLUR(float, 1.0, 4); break;
If it does not break plugin we probably can go for each noted plugin and try to find where they clip ....
