Time ago, I fell in the same trap: for fpGui I simply took the TGauge 
component which I had lifted from Delphi and adapted to Lazarus, with 
the changes required to make it work in fpGui environment.

Then Graeme pointed to me that I had been using copyrighted material, so 
I rewrote the code, making it different from the Delphi original.

Now in fpGui you may find a TGauge component, which has inherited the 
functionalities of the Delphi component (plus some extra) but doesn't 
share code with Delphi. Anybody can lift it from there, and adapt it 
back to Lazarus environment (where it originally came from).

I was planning to do it myself, but being quite busy and also lazy, I've 
been always postponing. If nobody does it before, one day or another 
I'll do it.
