Yup, you make a good point there. But both features were added mostly
'for completeness'. Painting float images should just work, because
they can be used everywhere else in Blender. And the texture brushes
were added because sculpt mode has a similar feature, so it would be
nice to have it working unified for all paint/sculpt modes.

I don't intend to duplicate gimp functionality, but would rather like to see
what we can add to the functionality in gimp and other image editors.
With procedural textures, texture synthesis and noodles, there's a lot of
possibilities for features that either don't fit into these 2d image editors,
or that are just not available in other (open source) apps.

I don't have plans to add new functionality to the 2d image editor for now,
except maybe undo, but rather work on other paint modes, getting the
brush functionality to work there, etc.

There lots of possibilities here, like having a brush node with speed,
pressure, tilt, direction outputs, or using time ipo's, or pydrivers/pynodes.
I'm not sure that could all work realtime, but it would be neat :).
