size-pressure relationship has been inverted for airbrush: complaints sought

Hi,

I just made a one-line change in cvs head, suggested by Dave Ahlswede, that inverts the relationship between pressure and brush size for the airbrush, on the grounds that this more accurately reflects the behavior of a real airbrush. People who use tablets should try it and see if they approve, and complain here if they don't.

Dave actually created a nice patch that makes it a tool option to invert the pressure-size relationship, but it seems better to avoid options unless people will actually use them. Hence this email. If you think it ought to be optional (or was a bad idea in the first place), please express your opinion.

Best,
-- Bill

I can't test that currently, but I imagine it's nice sometimes, but will be counterproductive in other cases -> I would like to have it as an option. And if there should be no option, I would prefer the known, not inverted behaviour.

BTW, how about using tilt for a closer airbrush simulation? That is, not having a fixed shape brush, but a tilt depending cone.

There is even a more generic solution proposed in http://bugzilla.gnome.org/show_bug.cgi?id=50638

That would be nice, but IMHO would require a real push in the tablet mappings, so limit, reference angles and so on could be set. When working with a real airbrush, you can move it with more freedom than a tablet pen (basically cos you hold it, not try to press it against the surface) and in some cases you can also move the target surface. I have been trying to do things with pipe brushes, and well... I found that I can choose between using the pen in really weird angles or create brushes with some tips that will never be used with normal handling, due lack of control in the angle limits.

Such a change wouldn't actually be that hard to do, we just need someone who's motivated enough to do it. If someone's interested, please speak up, I will try to give some tips on how to implement these features.
