 ||Proposed syntax for relative rectangles in themes||
 
+At any time, we introduce the notion of a reference rectangle, which is 
initialized to 0,0,0,0 initially, and is
+succesively set to each newly-created rectangle, so that we can always use the 
previous rectangle as a reference.
+
+Support may be added in the future to explicitely specify another rectangle as 
reference.
+
+Parts of a ''rect=a,b,c,d'' clause may be:
+* numbers : absolute positions like we already have
+* ''='' : same value as the same field in reference rect (alignement with 
reference)
+* +number or -number :
+ * for a and b, add this value to reference's c and d respectively (spacing 
from reference)
+ * for b and c, add this value to self's a and b (specify by width and height)
+* =+number or =-number : add this value to same field in reference rect (eg. 
consider reference as a container box)
+
