The current Render acceleration hooks are pretty low level; we need to spend some time designing a more comprehensive interface. The trouble is that Render provides so little structure to build upon, unlike the core protocol. We can place additional structure inside the render code and XAA to break down the current interface into more reasonable functions. However, it's hard to get excited about building accelerated implementations without a comprehensive test suite and when the spec is still a bit in flux. I've been working on the test suite with some students, but there's a steep learning curve and so not much progress has been made yet. The spec is almost finished as well; I've got to go rewrite the trapezoid specification to match our current thinking and I'd like to add some image transport requests. The trapezoid part won't have much of an effect on the architecture of any acceleration internals, but image transport may need to be exposed all the way to the bottom of the system. -keith _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
