Another one down

Today Kamalpreet and I solved another older issue we had in eCAD regarding selection of entities.

Earlier if there were multiple entities overlapping each other, user can’t select the entity beneath the other one because the bounding rectangle was obscuring the other.

And now by overloading the shape function we have been to adjust the bounding rectangle of the entity and now only the boundary of the entities are selectable.

This has been implemented for circle and line entities. Arc and ellipse will also be done in a day or so, just need to figure out a way to adjust their shape as well.
