Cocoa: ppc64 host support

Fix integer usage in the Cocoa backend: NSInteger is long on LP64.

http://developer.apple.com/mac/library/documentation/Cocoa/Reference/ApplicationKit/Classes/NSView_Class/Reference/NSView.html#//apple_ref/doc/uid/20000014-BBCFHHCD

This makes the graphical display show up on a ppc64 host.

v3:
- Confine NSInteger to Mac OS X v10.5 and later
