Use this when a mesh modifier adds vertices between existing ones — for example when subdividing, tessellating, or clipping geometry. The continuous vertex data (position, tint, texture coordinate, and the internal anti-aliasing data) is blended; the discrete per-vertex data that identifies the draw (clipping, element, texture, and gradient identifiers, and flags) is taken from .

Because that discrete data is copied rather than blended, and must belong to the same fill (the same draw within one VisualElement) — which is always the case when resampling the triangles of a single mesh. is not clamped: values outside the 0..1 range extrapolate beyond the endpoints.

Interpolates between two vertices, returning a new vertex a fraction of the way from to . Convenience overload that returns the result instead of writing to an out parameter — handy when the value is temporary.
