I attach a changeset incorporating Soren's and my precious patch. It
implements the following behavior for the fltk backend:
Keyboard Shortcuts (operate on the current axes):
a - autoscale
g - toggle grid

Mouse (operate on the axes below the mouse pointer)
left drag - pan
mouse wheel - zoom
right drag - rectangle zoom
left double click - autoscale

It laso chages the help buttons label from "H" to "?" which might help
people realize what it is.
Hopefully this compromise will satisfy all (Probably, as compromises
go, it'll just annoy everyone). Maybe in the future there will be some
mechanism to customize the backend, so everyone can be happy
