Panel can record custom commandlist like so:
```csharp
public class GlowPanel : Panel, IPanelDraw
{
static Material GlowMat = Material.FromShader( "shaders/ui_glow.shader" );
public void Draw( CommandList cl )
{
cl.Attributes.Set( "GlowColor", Color.Cyan );
cl.DrawQuad( Box.Rect, GlowMat, Color.White );
}
}```
