You are right. I haven't looked into it yet. Currently (as of r1955 and my 
local extension), I used the TestForIntersectionOfStraightLineSegments() to 
test rectangular/trapezoidal pads. Seems to work well...

I yet have to extend this work to do the Oval/Circle vs Trapezoid tests, but 
that can be done using GetClearanceBetweenSegments() function.

Jean-Pierre: During my "analysis" of the code, I encountered a function called 
checkLine(), which tests a line against some rectangle which is stored in 
DRC::m_xcliplo etc.
I think this function is really unintuitive (to be polite) as it uses some 
class members to do the test. Would you object if I removed that code and used 
something cleaner (as the functions I mentioned above)? Or is there any 
specific reason to do it with checkLine()?
