Functions

func Run 

func Run(run func())

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.
