ThreadsImporter

Last Revision:	Version 1.0.1, 2005-07-22 Updated to produce a universal binary. No code changes were required.
Build Requirements:	Xcode 2.1, Xcode 1.1+
Runtime Requirements:	Mac OS X 10.3 or later with QuickTime 6.4 or later.

ThreadImporter demonstrates importing and displaying still images on separate threads. For demonstration purposes only, this sample will also allow the use of non-thread safe components on separate threads. QuickTime 6.4 (on MacOS X 10.3 and later) introduces several new features that support execution of background tasks on multiple threads in a preemptive multitasking environment. This makes it possible to offload many tasks from your applications main thread to forestall blocking the user interface.

XCode 2.1 project builds universal binary.
