Better documented the difference between BeginListBox() and BeginChild() w/ ImGuiChildFlags_FrameStyle.

Browse Source 
BeginListBox() can't yet expose child flags because coarse clipping require query of stored size (same issue as with adding resize support to Tables).

// BeginListBox() is essentially a thin wrapper to using BeginChild()/EndChild() with the ImGuiChildFlags_FrameStyle flag for stylistic changes + displaying a label.
// You may be tempted to simply use BeginChild() directly, however note that BeginChild() requires EndChild() to always be called (inconsistent with BeginListBox()/EndListBox()).
// Using the generic BeginListBox() API, you have full control over how to display the combo contents.
// (your selection data could be an index, a pointer to the object, an id for the object, a flag intrusively
// stored in the object itself, etc.)
