Therefore + it is suitable for creating shapes spreading over larger areas of the + screen, avoiding the performance penalty for texture uploads or framebuffer + blits. + + Nonetheless it is important to be aware of performance implications, in + particular when the application is running on the generic PathItem + implementation due to not having support for accelerated path rendering. + The geometry generation happens entirely on the CPU in this case, and this + is potentially expensive. Changing the set of path elements, changing the + properties of these elements, or changing certain properties of the + PathItem itself all lead to retriangulation on every change. Therefore, + applying animation to such properties can heavily affect performance on + less powerful systems. If animating properties other than stroke and fill + colors is a must, it is recommended to target systems providing + \c{GL_NV_path_rendering} where the cost of path property changes is much + smaller. + + \note The types for specifying path elements are shared between PathView + and PathItem. However, not all PathItem implementations support all path + element types, while some may not make sense for PathView.
