[Bf-committers] water painting

[bjornmose]

Hi all,
Existing code for image manipulation is not that bad. There is are 
canvas, brush, image classes in __/img/intern for ages. Integration of 
that in UI however looks like a quick hack for testing purpose. It even 
has a #ifdef, so i assume this was never meant for release this way.

I started cleaning up the mess a bit by dragging the code out of space.c 
and abusing the floating paint panel to make a UI. Well, still undecided 
is where settings of the tools should be stored ( nasty global variables 
atm ). After tuhopuu2 break down i ported it to bf and keep a special 
privat CVS tree in sync for that. Patches are available there:

On the other hand i think it does not make very much sense to recode 
gimp, photoshop and co in blender. It's hard for me to draw the line 
between 'basic darwing tools' that should be part of blender and 
'advanced image manipulation' better to keep out.
