Passage: Quadratic and cubic Bézier curves are most common. Higher degree curves are more computationally expensive to evaluate. When more complex shapes are needed, low order Bézier curves are patched together, producing a composite Bézier curve. A composite Bézier curve is commonly referred to as a "path" in vector graphics languages (like PostScript), vector graphics standards (like SVG) and vector graphics programs (like Artline, Timeworks Publisher, Adobe Illustrator, CorelDraw and Inkscape). To guarantee smoothness (C1 continuity), the control point at which two curves meet must be on the line between the two control points on either side.

Question: What is one brand of vector graphic language?
