[Bf-funboard] Thoughts on multi-select mode.

[joe]

Our selection system is based on flushing, e.g. if you select an edge
it selects the verts, and if you select all the edges of a face, that
face is selected, etc.

To change this would require quite a bit of thinking, especially of
what this would mean for the tools code.

Multiselect mode can be a pain for this reason, but removing flushing
from it would be too big of a change, I think, especially since users
expect the flushing, and we'd probably have to remove it from all
selection modes.  Still, if you can think of a nice way to handle
this, we always appreciate feedback. :)
