    I'm surprised that XFree86 seems to be unconcerned with the 18-24
month timeframe in which most PC graphics hardware will have fully
programmable transform and raster engines, huge amounts of per-pixel
memory, and support high-precision floating point throughout the
graphics pipeline, among other good stuff. In this context, whether or
not a (frex) 35%-odd memory penalty for stodgy old bilinear texture
filtering is acceptable, seems a bit shortsighted.
