I belive it could be possible but this would require go deep inside MuPDF sources. I have no idea how they inperpolate. I think it's done during rasterization of vector fonts and graphics so the rasterizer would need to be rewritten. Main application only tell target DPI and the engine will provide pointer to target bitmat that I simply draw (internal representation is 32bit truecolor BGRA so if you have 32bpp mode it is fitted 1:1 without any recalc. If you have 24/16/8bpp mode, recalculation is needed but also output data are smaller so less PCI bus load to fill the framebuffer...)
