Functions
int	inactiveOpacityEnumToAlpha (InactiveOpacity inactiveOpacity)
	Map InactiveOpacity enum to corresponding alpha value.

	Map InactiveOpacity enum to corresponding string value.

Variables
const InactiveOpacity	DEFAULT_INACTIVE_OPACITY_ENUM = INACTIVE_OPACITY_64
	Default inactie opacity is not 0 so we see something, and not 255 which applies when active.

Enumeration Type Documentation

InactiveOpacity

enum InactiveOpacity

Enum for opacity/alpha values used for segments that are not currently under hover.

Just a few values are needed since a continuous spectrum over the whole range would require multiple up/down steps before any significant change could be seen
