Re: [Gimp-developer] Enhanced smudge tool : Smudge with painting

[<b91502038 ntu edu tw>]

Agree. I also hope that someone could suggest a better name because English 
is not my native language. The names can be discussed.

The UI texts I added:
No erasing effect
tooltip: Never decrease alpha of existing pixels
Flow
tooltip: The amount of brush color to blend
Rate
tooltip: The strength of smudging

About the name "Flow", the main problem I met is if I gave a new name, it 
had to be added to paint dynamics too. (Without dynamics this parameter has 
little use.)
In that experiment I just picked a parameter not used by smudge for quick 
implementing (Flow is only used by Airbrush now). And I thought the word 
"Flow" was somewhat reasonable here, like the amount of pigment in water 
color.

Not sure witch way is better, use the name "Flow" and explain it in a 
tooltip, rename it and consider the compatibility with Airbrush, or add a 
new parameter to dynamics.

Talk about a experience I learned GIMP. "Rate" is another parameter not used 
by all paint tools. Airbrush, Smudge, and Convolve use it but have different 
meanings and have no tooltips in current version of GIMP. I got comfused 
until I realized that they have different meanings.
But the paint dynamics system might become too complex if 3 different 
parameters were used.
So I think exactly naming will have drawbacks in paint dynamics, but a good 
tooltip can help.

About the boolean toggle, set Flow=0 will disable finger-painting and acts 
as original smudge tool. I think a toggle and a scale control are a little 
more complex than a scale control only. Just my opinion.
