It's not quite the same as Gimp's direct and indirect painting mode, but it was meant to make sure you could, in one stroke, repeatedly go over the same area without making the result darker.
Ok I've implemented it right now.
Please check it out :D (the others too of course).
Photoshop actually only works with indirect painting.
I agree that we should remove the "Painting Mode" option from the brushes.
Internally we need the distinguishing between direct and indirect 
painting of course.
But we don't need it in the UI anymore.
The Photoshop way is actually pretty smart. It behaves like if you would 
blend between
"build up" and "wash" mode.

The brushes that work only in direct painting mode don't have the 
"Painting Mode" option anyway
and for the brushes that have this option we should set the painting 
mode fixed to indirect.
