The purpose of this library is to be the equivalent of libXcursor in the X world. This library is compatible with X cursor themes and loads them directly into an shm pool making it easy for the clients to get buffer for each cursor image. The code for handling the X cursor theme was taken from libXcursor. The files cursor/xcursor.[ch] are a stripped down version of that library containing only the interfaces necessary for implementing the wayland counterpart.
