* You may freely copy,distribute and re-use the code in this example. NeXT
* disclaims any warranty of any kind, expressed or implied, as to its fitness
* for any particular purpose
*
* This file and its associated .m file define a data structure and set of
* functions aimed at facilitating the use of user paths. Here is a simple
* example:
*
* UserPath *arect;
* arect = newUserPath(); // creates an empty user path
* beginUserPath(arect,YES); // initialize user path and cache
* UPmoveto(arect,0.0,0.0); // add moveto to userpath; update bounding box
* UPrlineto(arect,0.0,100.0); // add rlineto to path; update bounding box
* UPrlineto(arect,100.0,0.0); // add rlineto to path; update bounding box
* UPrlineto(arect,0.0,-100.0); // add rlineto to path; update bounding box
* closePath(arect); // close path
* endUserPath(arect,dps_stroke); // close user path and specify operator
* sendUserPath(arect);
*
* As you will note, the set of routines manage the allocation and growth of
* the operator and operand arrays, as well as the calculation of the bounding
* box. A user path created via these functions may be optionally cached down
* at the window server, or repeatedly sent down. The user paths created by
* this set of functions are all allocated in a unique zone.
*
* Note: the associated file is a .m file because it pulls in some .h files
* which reference objective C methods.
