You removed the ability for a driver to support accelerated component alpha on a XFree 4.4.0 binary. If this is now the most common case then why wouldn't a driver want the opportunity to support that? Seems like the driver should be required to punt that rather than Xaa punting for them. Looking at the XAADoComposite function, it isn't very large so a driver could just hook at that level and pull a copy of that function into the driver minus the component alpha check and be able to support accelerated component alpha. There also seems to be a check that punts anything with a transform which also eliminates a large number of useful RENDER cases. (Do all stretches have a transform?) Seems like a driver that wanted to support RENDER well would have to hook at the Composite level currently so it isn't really a big deal that component alpha doesn't get passed through to the driver. There still remains the issue of why would the newer font libs use component alpha when that removes all opportunity for acceleration. Is there a way for the libs to determine that component alpha is an unaccelerated path? -Matt _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
