DESCRIPTION
     Tk_GetCapStyle places in *capPtr the X cap style correspond-
     ing to string.  This will be one of the values CapButt, Cap-
     Projecting, or CapRound.  Cap styles are typically used in X
     graphics  contexts  to  indicate how the end-points of lines
     should be capped.  See the X documentation  for  information
     on what each style implies.

     Under normal circumstances the return value  is  TCL_OK  and
     interp  is  unused.   If  string doesn't contain a valid cap
     style or an abbreviation of one  of  these  names,  then  an
     error  message  is  stored  in  interp->result, TCL_ERROR is
     returned, and *capPtr is unmodified.

     Tk_NameOfCapStyle is the logical inverse of  Tk_GetCapStyle.
     Given  a  cap style such as CapButt it returns a statically-
     allocated string corresponding to cap.  If cap isn't a legal
     cap style, then ``unknown cap style'' is returned.
