Detailed Description

CCPoint extensions based on Chipmunk's cpVect file.

These extensions work both with CCPoint and cpVect.

The "ccp" prefix means: "CoCos2d Point"

Examples:

• ccpAdd( ccp(1,1), ccp(2,2) ); // preferred cocos2d way
• ccpAdd( CCPointMake(1,1), CCPointMake(2,2) ); // also ok but more verbose
• cpvadd( cpv(1,1), cpv(2,2) ); // way of the chipmunk
• ccpAdd( cpv(1,1), cpv(2,2) ); // mixing chipmunk and cocos2d (avoid)
• cpvadd( CCPointMake(1,1), CCPointMake(2,2) ); // mixing chipmunk and CG (avoid)
