// ImDrawList: Helper function to calculate a circle's segment count given its radius and a "maximum error" value.
// FIXME: the minimum number of auto-segment may be undesirably high for very small radiuses (e.g. 1.0f)
#define IM_DRAWLIST_CIRCLE_AUTO_SEGMENT_MIN 12
// Estimation of number of circle segment based on error is derived using method described in https://stackoverflow.com/a/2244088/15194693
// Number of segments (N) is calculated using equation:
// N = ceil ( pi / acos(1 - error / r) ) where r > 0, error <= r
// Our equation is significantly simpler that one in the post thanks for choosing segment that is
// perpendicular to X axis. Follow steps in the article from this starting condition and you will
// will get this result.
//
// Rendering circles with an odd number of segments, while mathematically correct will produce
// asymmetrical results on the raster grid. Therefore we're rounding N to next even number (7->8, 8->8, 9->10 etc.)
