Subject: [PATCH] app: add GimpTransformGridTool::dynamic-handle-size property

Add a boolean GimpTransformGridTool::dynamic-handle-size property,
which controls whether the handle sizes are adjustment dynamically
according to the grid's size, or remain fixed.  This property is
TRUE by default, to maintain the current behavior.
