We really do want single precision here to be consistent with the graphics
library, Invert/Multiply used in gxipixel.c is exactly what is needed for
Postscript and PDF images and it must be done in single precision to be
compatible with Adobe.  Also, I haven't seen the need for doubles on HP
printers but the PCL specification is less clear on required precision.  Maybe
we can find another solution if you can attach the file that prompted the
change.
