 Here it is inserted into an electric light symbol definition.  The code is between the lines with % % %.  It creates a green insertion point, a red origin point that represents the (0u, 0u) origin of the symbol, a light blue rectangle that represents the loci of the alignment options (left, top-left etc), and a grey unit symbol size. Note that this code requires that T:= ... rotated BEFORE aligned.  If your symbol uses T:= ... aligned BEFORE rotated, then the code needs to be modified slightly.
-After writing the code, I realised that this symbol was in fact larger than 0.7u in the y direction, the symbol is not centered around around its (0u,0u) coordinates and it is just a bit (but probably acceptably) larger than u in size!
+After writing the code, I realised that this symbol was in fact larger than 0.7u in the y direction, therefore the U: variable is not tall enough, the symbol is not centered around around its (0u,0u) coordinates and it is just a bit (but probably acceptably) larger than u in size!
