Detailed Description

The Cairo implementation of the graphics abstraction layer.

View item to draw an origin marker.

Quote from Wikipedia: " Cairo is a software library used to provide a vector graphics-based, device-independent API for software developers. It is designed to provide primitives for 2-dimensional drawing across a number of different backends. "

Cairo offers also backends for PostScript and PDF surfaces. So it can be used for printing of KiCad graphics surfaces as well.
