BackgroundFlag

This flag is used by most functions that modify a cell background color. It defines how the console's current background color is used to modify the cell's existing background color.

See the documentation for TCOD::Color for details on how color arithmetic works when referenced below.

When equations are listed below, these are applied to each individual component in turn, with new being the component for the new color, old being the one for the current one, and white standing in for the maximum value for a color component (255).

TCOD::BKGND_NONE

The cell's background is not modified.
TCOD::BKGND_SET

The cell's background is replaced with the new color.
TCOD::BKGND_MULTIPLY

The cell's background is multiplied with the new color.
TCOD::BKGND_LIGHTEN

Each of the components of the cell's background is replaced with the respective component of the new color if it is lighter.
TCOD::BKGND_DARKEN

Each of the components of the cell's background is replaced with the respective component of the new color if it is darker.
TCOD::BKGND_SCREEN

The cell's background color is modified according to the following operation:
```
white - ( white - old ) * ( white - new )
```
TCOD::BKGND_COLOR_DODGE

The cell's background color is modified according to the following operation:
```
new / ( white - old )
```
TCOD::BKGND_COLOR_BURN

The cell's background color is modified according to the following operation:
```
white - ( white - old ) / new
```
TCOD::BKGND_ADD

The new color is added to the cell's background.
TCOD::BKGND_ADDALPHA

Use this as a macro with a float parameter between 0 and 1. The cell's background color is modified according to the following operation:
```
old + alpha * new
```
TCOD::BKGND_BURN

The cell's background color is modified according to the following operation:
```
old + new - white
```

TCOD::BKGND_OVERLAY

The cell's background color is modified according to the following operation:

2 * new * old                                 # if the component is >= 128
white - 2 * ( white - new ) * ( white - old ) # if the component is <  128

TCOD::BKGND_ALPHA

Use this as a macro with a float parameter between 0 and 1. The cell's background color is modified according to the following operation:
```
( 1 - alpha ) * old + alpha * ( new - old )
```
TCOD::BKGND_DEFAULT

Use the console's default background flag. See TCOD::Console::set_background_flag.

Distribution

These values are used by TCOD::Random to generate random numbers.

TCOD::DISTRIBUTION_LINEAR

This is the default distribution. It will return a number from a range min-max. The numbers will be evenly distributed, ie, each number from the range has the exact same chance of being selected.
TCOD::DISTRIBUTION_GAUSSIAN

This distribution does not have minimum and maximum values. Instead, a mean and a standard deviation are used. The mean is the central value. It will appear with the greatest frequency. The farther away from the mean, the less the probability of appearing the possible results have. Although extreme values are possible, 99.7% of the results will be within the radius of 3 standard deviations from the mean. So, if the mean is 0 and the standard deviation is 5, the numbers will mostly fall in the (-15,15) range.
TCOD::DISTRIBUTION_GAUSSIAN_RANGE

This one takes minimum and maximum values. Under the hood, it computes the mean (which falls right between the minimum and maximum) and the standard deviation and applies a standard Gaussian distribution to the values. The difference is that the result is always guaranteed to be in the min-max range.
TCOD::DISTRIBUTION_GAUSSIAN_INVERSE

Essentially, this is the same as TCOD::DISTRIBUTION_GAUSSIAN. The difference is that the values near +3 and -3 standard deviations from the mean have the highest possibility of appearing, while the mean has the lowest.
TCOD::DISTRIBUTION_GAUSSIAN_RANGE_INVERSE

Essentially, this is the same as TCOD::DISTRIBUTION_GAUSSIAN_RANGE, but the min and max values have the greatest probability of appearing, while the values between them, the lowest.
