Hi, A few comments from my perspective here, mainly coming from frustration at the number of times I've had to tell clients or users that JavaFX isn't a viable option for them ..

I agree that's a difficult one, but also surely not an insurmountable one?! There are precedents around Java APIs that provide querying and access to optional support on a platform by platform basis. A library integrating JavaFX with some other platform / renderer specific API is always going to have to handle the situation by either failing gracefully or falling back to a less performant alternative. > Traditional stateful APIs like > OpenGL make it far too easy for external code to screw up the > rendering context anyway, so exposing JavaFX's own context would > be a bad idea. I remain of the view that this shouldn't really be that concerning?! It's a bug in the library if it does so. The current PixelBuffer API already allows enough access for a library to *really* screw up the rendering context, by bringing the whole thing crashing down. But, concurrency issues aside, adding that access has been a real boon. With access comes responsibility. > JavaFX _does_ have a software renderer. What if we could have JavaFX > work with entirely software rendering into an offscreen BufferedImage? Why BufferedImage? What about a reuse / extension / parallel of PixelBuffer? That could allow a range of implementation and the potential for using renderers that can output without a visible window to do this while at least keeping all pixel data off heap?
