By the way, how do you know what is the "right" gamma curve? I think I 
copied this from the generic st7735r driver in fbtft, but I noticed that 
there is also a different curve for the Adafruit 1.8" display in fbtft. 
I'm wondering if I should have used that one instead. I can't really 
tell a difference looking at the display.
