Size barcodes in whole printer dots and check codes for every row - #27
Merged

Conversation
Barcodes were stretched to a chosen width in millimetres, so bars landed between printer dots and printed unevenly and could not be scanned. Bars are now the fewest whole printer dots that scan reliably (0.25 mm), set from a printer resolution option and aligned to the printer's dot grid, with blank margins of 10 bar widths. The barcode width settings are gone; the width follows from the longest code value. QR codes and barcodes are checked against every row being printed. Blank values, characters a barcode cannot hold, codes too large to fit, stacked fields taller than the label, and QR squares too small to scan block export, with a message naming the worst value and its row. The preview shows an outline in place of a code that cannot print. Choosing a barcode now starts with fields above and below it. The row table gains a search box with select and deselect buttons for the matching rows. Print ticks are kept by dataset row, so they survive searches and changes to the row range or filters.
