*
* Light management has been refactored to provide a cleaner class-based interface.
* Also, now all values are stored as integer, no more floats that could generate
* rounding errors.
*
* Two singletons are now used to control the state of the light.
* - light_state (LightStateClass) stores the color / white temperature and
* brightness. Use this object to READ only.
* - light_controller (LightControllerClass) is used to change light state
* and adjust all Settings and levels accordingly.
* Always use this object to change light status.
*
* As there have been lots of changes in light control, here is a summary out
* the whole flow from setting colors to drving the PMW pins.
*
* 1. To change colors, always use 'light_controller' object.
* 'light_state' is only to be used to read current state.
* .a For color bulbs, set color via changeRGB() or changeHS() for Hue/Sat.
* Set the overall brightness changeBri(0..255) or changeDimmer(0..100%)
* RGB and Hue/Sat are always kept in sync. Internally, RGB are stored at
* full range (max brightness) so that when you reduce brightness and
* raise it back again, colors don't change due to rounding errors.
* .b For white bulbs with Cold/Warm colortone, use changeCW() or changeCT()
* to change color-tone. Set overall brightness separately.
* Color-tone temperature can range from 153 (Cold) to 500 (Warm).
* CW channels are stored at full brightness to avoid rounding errors.
* .c Alternatively, you can set all 5 channels at once with changeChannels(),
* in this case it will also set the corresponding brightness.
*
* 2.a After any change, the Settings object is updated so that changes
* survive a reboot and can be stored in flash - in saveSettings()
* .b Actual channel values are computed from RGB or CT combined with brightness.
* Range is still 0..255 (8 bits) - in getActualRGBCW()
* .c The 5 internal channels RGBWC are mapped to the actual channels supproted
* by the light_type: in calcLevels()
* 1 channel - 0:Brightness
* 2 channels - 0:Coldwhite 1:Warmwhite
* 3 channels - 0:Red 1:Green 2:Blue
* 4 chennels - 0:Red 1:Green 2:Blue 3:White
* 5 chennels - 0:Red 1:Green 2:Blue 3:ColdWhite 4:Warmwhite
*
* 3. In LightAnimate(), final PWM values are computed at next tick.
* .a If color did not change since last tick - ignore.
* .b Extend resolution from 8 bits to 10 bits, which makes a significant
* difference when applying gamma correction at low brightness.
* .c Apply Gamma Correction if LedTable==1 (by default).
* Gamma Correction uses an adaptative resolution table from 11 to 8 bits.
* .d For Warm/Cold-white channels, Gamma correction is calculated in combined mode.
* Ie. total white brightness (C+W) is used for Gamma correction and gives
* the overall light power required. Then this light power is split among
* Wamr/Cold channels.
* .e Gamma correction is still applied to 8 bits channels for compatibility
* with other non-PMW modules.
* .f Apply color balance correction from rgbwwTable[].
* Note: correction is done after Gamma correction, it is meant
* to adjust leds with different power
* .g If rgbwwTable[4] is zero, blend RGB with White and adjust the level of
* White channel according to rgbwwTable[3]
* .h Avoid PMW values between 1008 and 1022, issue #1146
* .i Scale ranges from 10 bits to 0..PWMRange (by default 1023) so no change
* by default.
* .j Apply port remapping from Option37
* .k Invert PWM value if port is of type PMWxi instead of PMWx
* .l Apply PWM value with analogWrite() - if pin is configured
*

// This class has 2 independant slots
// 1/ Brightness 0.255, dimmer controls both RGB and WC (warm-cold)
// 1/ RGB and Hue/Sat - always kept in sync and stored at full brightness,
// i.e. R G or B are 255
// briRGB specifies the brightness for the RGB slot.
// If Brightness is 0, it is equivalent to Off (for compatibility)
// Dimmer is Brightness converted to range 0..100
// 2/ White with colortone - or CW (Cold / Warm)
// ct is 153..500 temperature (153=cold, 500=warm)
// briCT specifies the brightness for white channel
//
// Dimmer (0.100) is automatically derived from brightness
//
// INVARIANTS:
// 1. RGB components are always stored at full brightness and modulated with briRGB
// ((R == 255) || (G == 255) || (B == 255))
// 2. RGB and Hue/Sat are always kept in sync whether you use setRGB() or setHS()
// 3. Warm/Cold white channels are always stored at full brightness
// ((WW == 255) || (WC == 255))
// 4. WC/WW and CT are always kept in sync.
// Note: if you use setCT() then WC+WW == 255 (both channels are linked)
// but if you use setCW() both channels can be set independantly
// 5. If RGB or CT channels are deactivated, then corresponding brightness is zero
// if (colot_tone == LCM_RGB) then briCT = 0
// if (color_tone == LCM_CT) then briRGB = 0
// if (colot_tone == LCM_BOTH) then briRGB and briCT can have any values
//
// Note: If you want the actual RGB, you need to multiply with Bri, or use getActualRGBCW()
// Note: all values are stored as unsigned integer, no floats.
// Note: you can query vaules from this singleton. But to change values,
// use the LightController - changing this object will have no effect on actual light.
