// Run is essentially the main function of PixelGL. It exists mainly due to the technical
// limitations of OpenGL and operating systems. In short, all graphics and window manipulating calls
// must be done from the main thread. Run makes this possible.
//
// Call this function from the main function of your application. This is necessary, so that Run
// runs on the main thread.
//
// func run() {
// // interact with Pixel and PixelGL from here (even concurrently)
// }
//
// func main() {
// pixel.Run(run)
// }
//
// You can spawn any number of goroutines from your run function and interact with PixelGL
// concurrently. The only condition is that the Run function is called from your main function.
func Run(run func()) {

}

}
You can’t perform that action at this time.
