Ok. The code is ready for integration. Anyone like to give it a try?

I've not decided yet which settings should go to the system-gschemrc 
file:
Whether the magnetic mode is on/off by default, and all tuning variables 
in the top of the o_net.c file
-------
/* magnetic options */
/* half size of the magnetic marker on the screen. */
#define MAGNETIC_HALFSIZE 6

/* define how far the cursor could be to activate magnetic */
#define MAGNETIC_PIN_REACH 50 
#define MAGNETIC_NET_REACH 20
#define MAGNETIC_BUS_REACH 30

/* weighting factors to tell that a pin is more important than a net */
#define MAGNETIC_PIN_WEIGHT 5.0
#define MAGNETIC_NET_WEIGHT 2.0
#define MAGNETIC_BUS_WEIGHT 3.0
-----

Which variables should go into the configuration file?


Another minor thing is that if your in the magnetic mode and your close 
to a possible connection and you don't want to connect.

You can zoom in to make the distance bigger and the magnetic marker 
disappears. 
The other possibility is to use a modifier key:
* overwrite the nonorthogonal mode when using magnetic nets and use the
  CTRL modifier key
* use the ALT modifier key

Comments are very welcome.
