This builds on that paper, apparently:

> Yuksel [2024] explained how Seiler interpolation can be used to evaluate polynomial curves, including B´ezier curves, and noted that GPU linear interpolation could be used for the initial linear interpolation steps, with the remaining interpolations done in shader code.

> In this paper, we present the details of evaluating Bézier curves using hardware-accelerated linear texture interpolation and show how to perform all interpolations on the hardware, using both the de Casteljau algorithm and Seiler interpolation. We also compare performance and accuracy against curves evaluated as polynomials in shader code.

Ah yes. That covered some Bezier interpolations; this covers all. Thanks for the correction.
