* Function PushTrack
|

|
* In this case, it tries to push the new track out of the conflicting track's

* clearance zone. This gives us a cheap mechanism for drawing tracks that
|

* tightly follow others, independent of grid settings.
|
|
*
|
|
* KNOWN BUGS:
|
|
* - we do the same sort of search and calculation up to three times:
|
|
* 1) we search for magnetic hits (in controle.cpp)
|
|
* 2) we check if there's a DRC violation in the making (also controle.cpp)
|
|
* 3) we try to fix the DRC violation (here)
|
|
* - if we have a magnetic hit and a DRC violation at the same time, we choose
|
|
* the magnetic hit instead of solving the violation
|
|
* - should locate conflicting tracks also when we're crossing over them
