Corrected a mistake that caused the altivec test to be turned off on PowerPC machines
Turned off coalesced graphics updates for all platforms on Mac OS 10.4.4 and higher
Switched compiler to GCC 4.0 on PowerPC. This provides some boost to floating point and AltiVec scores, and these have been recalibrated accordingly. This also raises Xbench's system requirements to 10.3.9 or higher.
Revised machine database to include the MacBook, Intel iMac and several other models
Added code to dynamically load machine database on launch from the Xbench website
Added support for temporarily turning off beam sync on Tiger while running graphics tests
Fixed an issue that causes Xbench to fail to launch on Leopard
