Creating a MarkupGrid itemComponent in code.

As far as I'm aware, you can't do it. 
[spoiler=on class-name as a factory in RSG:18uh2wpi]There's a compilation step when using Scene Graph XML that only happens once on startup.  During that step is where you define a component and give it a name.

<component name = "MyPoster" extends = "Poster" >

Then later you refer to this component by name.  

m.grid = createObject("roSGNode","MarkupGrid")
m.grid.translation = "[100,100]"
m.grid.itemComponentName = "MyPoster"

What you've done with makeGridItem() is created a single instance of the Rectangle component type and given that instance a unique id of `gridItem`.  MarkupGrid isn't looking at id's of object instances with itemComponentName, it's looking at the registry of defined component types.[/spoiler:18uh2wpi]
