Hello,

Is there a way to change the window icon in GLMakie?

Looks like it is set [here](https://github.com/MakieOrg/Makie.jl/blob/master/GLMakie/src/screen.jl#L239), so if you don’t care about messing with undocumented internal state, this seems to work:

```julia
using FileIO # For loading images
using ColorTypes # for converting to RGBA

fig = Figure()
# depending on image storage, you may or may not need the conversion to RGBA
newicon = RGBA.(load("myimage.png"))
GLMakie.GLFW.SetWindowIcon(
    fig.scene.current_screens[1].glscreen,
    reinterpret(NTuple{4, UInt8}, newicon))

```
