Empty insets should use a minimal amount of space, especially when they are part of a built-in macro in lib/symbols. With this change, blue rectangles signal actually editable places. Empty macros in editable data are shown as grey boxes, but they do not appear when further nested. This is done by adding a new type BOX of MathRow::Element object and a MetricsInfo::macro_nesting that keeps track of macros (and is reset to 0 in editable macro arguments).
