[Gimp-developer] Incremental issue behavior



In the documentation has wrote that if is enable 'incremental' on tool options, the opacity is full always.
"The incremental check-box does not seems to work as everyone expect. If 
it is deactivated (the default value) the maximum effect of a single 
stroke is determined by the opacity set in the opacity slider. If the 
opacity is set to less than 100, moving the brush over the same spot 
will increase the opacity if the brush is lifted in the meantime. 
Painting over with the same stroke has no such effect. If Incremental is 
active the brush will paint with full opacity independent of the 
slider's setting. This option is available for all paint tools except 
those which have a “rate” control, which automatically implies an 
incremental effect."
So, if you have the paint dynamic with Opacity parameter 'on' this is 
not true apparently ;-)
Is possible modeling the behavior of opacity with a different gains... 
for instance, if you use an small rate, around ~10, on 'opacity' slider 
(tool options).
Then, I am not sure if this is correct or is a secondary effect not 
expected... so, this is an emerging feature.
thanks
