sorry for absence of easy answer ... You are right: I cannot understand the operation by superficial reading of the code. Each plugin has all the strings that I thought could discriminate their operation. Trying to read the code of histogram.C I found:
CLAMP(output, 0, 1.0); case BC_RGBA_FLOAT // uint8 rgb is 8 bit, all others are converted to 16 bit RGB
The first CLAMP might indicate the normalized range (0, 1.0); The comment seems to indicate that these are integer calculations (8 or 16 bits); etc. Plus in the mailing-list (later reported in the manual) GG was talking about 8- or 10-bit calculations, not 16-bit.
well, does histogram beizer works better? do you have simple test file we can load, add plugin in rgba_float), output and easily see that it clipped?
In short, I don't have the ability to discriminate how plugins work. I thank you for the explanations and the tests you have pointed out.
