/*! \brief Draw a bounding box or outline for OBJECT placement
*
* \par Function Description
* This function draws either the OBJECTS in the place list
* or a rectangle around their bounding box, depending upon the
* currently selected w_current->actionfeedback_mode. This takes the
* value BOUNDINGBOX or OUTLINE.
*
* The function applies manhatten mode constraints to the coordinates
* before drawing if the CONTROL key is recording as being pressed in
* the w_current structure.
*
* The "drawing" parameter is used to indicate if this drawing should
* immediately use the selected feedback mode and positioning constraints.
*
* With drawing=TRUE, the selected conditions are used immediately,
* otherwise the conditions from the last drawing operation are used,
* saving the new state for next time.
*
* This function should be called with drawing=TRUE when starting a
* rubberbanding operation and when otherwise refreshing the rubberbanded
* outline (e.g. after a screen redraw). For any undraw operation, should
* be called with drawing=FALSE, ensuring that the undraw XOR matches the
* mode and constraints of the corresponding "draw" operation.
*
* If any mode / constraint changes are made between a undraw, redraw XOR
* pair, the latter (draw) operation must be called with drawing=TRUE. If
* no mode / constraint changes were made between the pair, it is not
* harmful to call the draw operation with "drawing=FALSE".
*
* \param [in] w_current GSCHEM_TOPLEVEL which we're drawing for.
* \param [in] drawing Set to FALSE for undraw operations to ensure
* matching conditions to a previous draw operation.
