IBLines

I got more pissed off than usual about IB's lack of line drawing
capability one day (yes, I know about the Box trick), so I decided 
to do something about it.

This is a 2.x IB palette that adds some simple line-drawing capability
to IB.  You can drag lines off the palettes window and drop them into your
windows; the lines can be a variety of colors and alpha levels. The lines are
actually subclasses of Button, so they can perform actions
when clicked upon.  This might be useful for rigging up something
like a responsive state diagram.  You'd have a diagram of the steps a user
needs to go through up on the screen; to move from one state to another,
the user clicks on an arrow, and the interface moves to that new state.
You can form the connections inside of IB doing the usual control-drags,
just like setting up a button's target and action.

The lines can be enabled or disabled.  Each has its own color associated
with it.  By default, the enabled color is black, and the disabled color
dark grey.  You can change these around with either some buttons that set
the colors to the default greyscales on the NeXT Classic display, or
bring up a color panel. 

There are four lines: vertical, horozontal, "uphill", and "downhill".
You can drag each of these from the palette and drop them into your
window.  (Sorry, you can't switch between these types on the fly.)

You do the usual steps to get a palette to work with your project.  If
you have any questions about this, see NeXTanswers, ib.606.

Note that 2.x palettes are NOT compatible with 3.0.  You'd need to
rewrite it to get it to work.  I'm apparently the last person in the
known universe using primarily 2.x, and it will be a little while
before I routinely use 3.0.  Feel free to modify it, though.
