You propose SIMD optimization for the software fallback path. I wonder whether we should focus on one fast GPU path via GLSL, and have one precise, working, I-don't-care-how-slow CPU fallback. All hardware made the last few years will have a GPU we support.
I'm surprised at this statement, and suspect that it's not true.
In general we don't support GPU on most integrated intel graphics hardware on Win7. We are slowly starting to support this on Win8. But we actively blocklist a pretty sizeable chunk of graphics hardware/driver versions even on pretty modern computers.
In addition, our desktop strategy has us actively targeting emerging markets where WinXP is the dominant OS and is likely to remain that way for years to come.
Perhaps the correct answer here is to not support some kinds of filter effects on older hardware, rather than supporting them in very slow paths. Do we have a sense for whether especially CSS filters would gracefully degrade in general?
