Subject: [PATCH] Fixed the value of property FIXED_BBOX when saving a file; 
 it needs to be scaled down by "reducer" like all other values in the cell.
 Suggests a need to have property types other than string, so that a property
 type "rect" or "box" can be declared that is saved as a Rect and always
 scales without special hack handling of the specific string FIXED_BBOX. . .
