<doc>
This block creates a variable with a slider. \
Leave the label blank to use the variable id as the label. \
The value must be a real number. \
The value must be between the start and the stop.
The GUI hint can be used to position the widget within the application. \
The hint is of the form [tab_id@tab_index]: [row, col, row_span, col_span]. \
Both the tab specification and the grid position are optional.
