Unfortunately, there are several issues in RunOnMainThread: * RunOnMainThread cannot be portable: It is impossible to implement this correctly on mobiles. * RunOnMainThread doesn't make sense on mobiles: the rendering works on a different thread (goroutine) on mobiles. * RunOnMainThread can cause deadlocks very easily. Until we find a better solution, let's remove this. Closes #1945
