to the OpenGL backend.

use ">=" instead of ">" when checking for shadow tile overlaps

Is there a way that because the shadows are bigger, that the list items can accommodate for that extra space? That way the shadows of one don't overlap on the next list item?

It's a little bit tricky... How it supposed to look when there are decorations with big shadows and small shadows? Also, I think this is out of scope of this patch. :)

Maybe I will propose that in a different patch to address that.

Thanks
