Optimize rendering of two dimensional barcodes: defer upscale.
Defer upscaling as late as possible so that intermediary data
structures are smaller.
Made a couple of changes along the way to preserve the barcode
correctness and fix some padding issues.
For my example, this is a ~21x improvement in rendering time, down
from ~190ms per barcode to ~9ms.
