The graphics interface visible to programmers is the NeXTStep Window system and Display PostScript with NeXT/Pixar extensions. Theoretically, DPS doesn't know about pixels, color tables, and bit planes, so it would seem to be hard to put XWindows on top of it. Many vendors are doing the reverse---adding DSP to XWindows. I expect it is unlikely that NeXT will release the routines below DSP & NeXTStep because their graphics interface has the richest functionality I've seen and is fast. DSP is may be transparent enough to implement most of X. Windows are initially scaled at pixel dimensions. XSetFunction can be emulated with the DSP-Pixar compositing functions. Color tables may be a bit more tricky. (I have no relation to NeXT other than an experienced user.)
