Overlays two colours. The Alpha component of the top colour controls the blend.

Overlays two colours.

Calculates a linear blend between two extremes. Although the inputs are unlimited integers, the output is an integer in the byte range (0-255).

Find the closest point on or in a box given a test point. Arc extension is implied.

Fade a colour to transparency by linearly blending a parameter between extremes.

Calculates a suitable foreground color. If the background is lighter than 50%, the foreground will be darker, otherwise the foreground will be lighter.
