/* technical note about the lightness emulation
*
* we try to emulate something that looks like the Dream's
* non-linear LCD lightness, without going too dark or bright.
*
* the default lightness is around 105 (about 40%) and we prefer
* to keep full RGB colors at that setting, to not alleviate
* developers who will not understand why the emulator's colors
* look slightly too dark.
*
* we also want to implement a 'bright' mode by de-saturating
* colors towards bright white.
*
* All of this leads to the implementation below that looks like
* the following:
*
* if (level == MIN)
* screen is off
*
* if (level > MIN && level < LOW)
* interpolate towards black, with
* MINALPHA = 0.2
* alpha = MINALPHA + (1-MINALPHA)*(level-MIN)/(LOW-MIN)
*
* if (level >= LOW && level <= HIGH)
* keep full RGB colors
*
* if (level > HIGH)
* interpolate towards bright white, with
* MAXALPHA = 0.6
* alpha = MAXALPHA*(level-HIGH)/(MAX-HIGH)
*
* we probably want some sort of power law instead of interpolating
* linearly, but frankly, this is sufficient for most uses.
