Functions
VuoColor	VuoColor_valueFromString (const char *initializer)
	Parses the C string initializer, expected to contain a comma-separated quadruplet of decimal numbers, to create a new VuoColor.
char *	VuoColor_stringFromValue (const VuoColor value)
	Serializes value as a C string.
char *	VuoColor_summaryFromValue (const VuoColor value)
	Same as VuoColor_stringFromValue() — always shows the full value, since it's guaranteed to be pretty short.
VuoColor	VuoColor_makeWithHSLA (VuoReal h, VuoReal s, VuoReal l, VuoReal a)
	Returns a VuoColor with the given hue, saturation, lightness, alpha.
void	VuoColor_getHSLA (VuoColor color, VuoReal *h, VuoReal *s, VuoReal *l, VuoReal *a)
	Gets the hue, saturation, lightness, hue, alpha of a color.
