SKY_MARKER_DISC_CLEARANCE

constexpr Scalar SKY_MARKER_DISC_CLEARANCE = Scalar(12)

Description

Pixels the leader line clears the body's drawn disc by before the banner starts.

The banner must not sit on the thing it names. Twelve pixels is the smallest gap that still reads as a gap at the default editor font's 13-pixel line height — below that the banner's lower edge and a small body's disc merge into one blob.
