Add border style

[sebord]

Clear and concise description of the problem

The current QR code designed on canvas lacks an outer border. If you need to add an outer border, you need to design it separately in PhotoShop.

Suggested solution

Several styles of border buttons are preset. Each button represents a style of border. When the user clicks the button, the QR code designed on the current canvas can be placed into the selected border.
