Namespaces
namespace	rack
	Root namespace for the Rack API.

namespace	rack::color
	Utilities for `NVGcolor`

Functions
bool	rack::color::isEqual (NVGcolor a, NVGcolor b)
	Returns whether all RGBA color components are equal.

NVGcolor	rack::color::clamp (NVGcolor a)
	Limits RGBA color components between 0 and 1.

NVGcolor	rack::color::minus (NVGcolor a, NVGcolor b)
	Subtracts RGB color components elementwise.

NVGcolor	rack::color::plus (NVGcolor a, NVGcolor b)
	Adds RGB color components elementwise.

NVGcolor	rack::color::mult (NVGcolor a, NVGcolor b)
	Multiplies RGB color components elementwise.

NVGcolor	rack::color::mult (NVGcolor a, float x)
	Multiplies RGB color components by a scalar.

NVGcolor	rack::color::lerp (NVGcolor a, NVGcolor b, float t)
	Interpolates RGBA color components.

NVGcolor	rack::color::screen (NVGcolor a, NVGcolor b)
	Screen blending with alpha compositing.

NVGcolor	rack::color::alpha (NVGcolor a, float alpha)
	Multiplies alpha value by a scalar.

NVGcolor	rack::color::fromHexString (std::string s)
	Converts from hex string of the form "#RRGGBB" or "#RRGGBBAA".

std::string	rack::color::toHexString (NVGcolor c)
	Converts color to hex string of the form "#RRGGBB" if opaque or "#RRGGBBAA" if alpha < 255.
