The tool rail component allows the tool to register an icon
and button (and dynamic tooltip) in the tool rail on the
left side of the display. Adding a tool rail component to a
tool will cause the tool to be considered a modal tool,
and only one single modal tool can be active at any one
time. Modal tools are generally tools which take focus and
control of the cursor (e.g. selection, clipboards, entity
selection, etc) Global tools (tools which do not have a tool
rail) are generally things like property pages, settings,
etc - things that do not require an active cursor or
gameplay interaction
