idMenuWidget_CommandBar

Provides a paged view of this widgets children.  Each child is expected to take on the following
naming scheme.  Children outside of the given window size (NumVisibleOptions) are not rendered,
and will affect which type of arrow indicators are shown.

This transparently supports the "UseCircleForAccept" behavior that we need for Japanese PS3 SKU.
