For some reason HP has decided that their 8-bit gray displays should

be GrayScale instead of StaticGray.  This problem is compounded by
some program, probably MWM, which has preallocated some read/write
color cells, thus preventing us from allocating all 256 gray levels.
Grumble; work around this by only allocating 128 gray levels.
