It depends. If you need pixel-perfect rendering, then this is actually impossible, because either the spec (e.g. Render, which does exactly the opposite of what people expect with respect to some things, like rounding the wrong way) will specify behaviour you don't want, or in the case of hardware acceleration, it's unspecified. Case in point: you can't accelerate wide lines and have a strictly-conformant X server. The spec detailed the exact algorithm for how the lines had to be rasterised. For a start, it was horrendously ugly and the lines looked awful, but secondly, it means you can't use hardware acceleration, because you're not going to get lines that are pixel-perfect to the spec. So, there's not a great deal Flash could accelerate, even if it did want to. It does its own rasterising for very good reasons.
