-	This file initially included the code to output barcodes to PNG images. To this has been
-	added routines to ouput the symbol in a byte array for manipulation within an external
-	program - the difference can be seen as "PNG mode" and "BMP mode". The reason they have been
-	lumped together here is because they use much the same functions and so it saves memory to
-	put them together. The problem is that it means the "BMP mode" functions are not available
-	unless PNG encoding is enabled. This is a compromise and I hope it doesn't cause anybody problems.
