Docking: Added ImGuiDockNodeFlags_Dockspace instead of node internal IsDockspace toward allowing the DockBuilder API to create non-dockspace nodes.

When resizing from an edge, the border is more visible and better follow the rounded corners. Border rendering moved to RenderOuterBorders so it can be called in a different order for docking. (#1495, #822)

Docking: Fix a focusing issue where dock node wouldn't be moved to the front as expected.

Comments + clear out VisibleWinodw field (should have no effect)

Docking: Comments and renaming locals to facilitate debugging.
