SetCCursor
SetCCursor Set a color cursor
#include <Quickdraw.h> Color Quickdraw
void SetCCursor( cCrsr );
CCrs rHandle cCrsr ; address of color cursor data structure
SetCCursor installs a color cursor and expands the cursor to the current
screen depth.
cCrsr is the address of a CCrsr data structure containing the
information defining the desired new cursor's shape and color.
Returns: none

Notes: SetCCursor lets your application specify a multicolor cursor. By
expanding the cursor to the current screen depth, SetCCursor also helps
speed response time by making sure the cursor can be redrawn quickly.
If your application changes the cursor's shape or color information, first
invalidate the crsrXValid and crsrID fields and then call SetCCursor.
