I've run into problems using ajstarks' OpenVG library. What I want to achieve is blurred white lines running across the screen, but I can't quite understand how to use FillLinearGradient. Could someone give me a simple C example please? I couldn't work it out from the Go example that is provided in the library.
I'm trying to display something like the visual stimulus for this mouse seen here https://youtu.be/Kks05U96-9w
