Personally, I'd recommend trying to calibrate the display for sRGB and
use "Display_Gamma=srgb". At any rate, the setting should of course
match the display system's effective gamma, so a generic recommendation
of setting Display_Gamma to 2.2 falls a bit short.

Personally, I prefer Mike's approach of using separate "rotate"
statements, as I think it makes it a bit easier for the reader to see
what's happening; it'll also allow you to always use the same pattern
for sequences of rotations, regardless of whether or not they match the
standard X-Y-Z ordering.
