In this example, we create an LLRect object with the initial position (10, 20) and size (30, 40). We then call the stretch() method with a factor of 2.0, which doubles the size of the rectangle. Another example of using LLRect stretch is to stretch a rectangle to fit inside another rectangle:cpp LLRect rect1(10, 20, 30, 40); LLRect rect2(0, 0, 50, 50); rect1.stretchToFit(rect2); // Stretch rect1 to fit inside rect2 ``` In this example, we create two LLRect objects, rect1 and rect2. We then call the stretchToFit() method on rect1 with rect2 as the argument. This method scales rect1 as much as possible while still fitting it entirely inside rect2. The LLRect class and its stretch methods are part of the Linden Lab Viewer codebase, which is a C++ library for building virtual worlds like Second Life.
