Snap: improve performance of wireframe objects intersection.

Enhances the performance of mouse intersection checks for wireframe objects.
Details:
- Calculated the intersection with the mouse in 2D pixels first.
- Converted objects to a BVH Tree to reduce the number of edges checked against the mouse position.
