I am still learning Luxor.

I find two in-built tangent functions:

`circletangent2circles()`

makes circles of a particular radius tangential to two circles

`circlepointtangent()`

makes circles of a particular radius passing through a point and tangential to another circle

But I do not find in-built functions for other more common tangents,

like a tangent from a point to a circle, or a common tangent of two circles.

Is there any plan to add these functions?
