CopyPixMap
CopyPixMap Duplicate pixMap's structure to an existing pixmap
#include <Quickdraw.h> Color Quickdraw
void CopyPixMap( srcPm, destPm );
PixMapHandle srcPm ; pixel map to be copied
PixMapHandle destPm ; pixel map to hold a duplicate of srcPm
CopyPixMap copies the data of one pixel map into an other.
srcPm is the handle of an existing pixel map you wish to duplicate.
destPm is the handle of destination pixel map.
Returns: none

Notes: CopyPixMap copies the contents of the color table, giving the destination
PixMap its own.
The image is not copied -- only the pointer that is the pixMap's baseAddr
field (base address).
