DALI_PROPERTY_TABLE_BEGIN const float Dali::Internal::anonymous_namespace{path-impl.cpp}::BezierBasisCoeff[]
Initial value:
= { -1.0f, 3.0f, -3.0f, 1.0f,
3.0f, -6.0f, 3.0f, 0.0f,
-3.0f, 3.0f, 0.0f, 0.0f,
1.0f, 0.0f, 0.0f, 0.0f }

These coefficient arise from the cubic polynomial equations for a bezier curve.

A bezier curve is defined by a cubic polynomial. Given two end points p0 and p1 and two control points cp0 and cp1, the bezier curve will be defined by a polynomial in the form f(x) = a3*x^3 + a2*x^2 + a1*x + a0 with this restrictions: f(0) = p0 f(1) = p1 f'(0) = 3*(cp0 - p0) f'(1) = 3*(p1-cp1)
