Build a tool to define SVG

[tauthomas01]

Issue

New icon requests require manual review and such process takes time. What if we could create a tool that could simplify the workflow and reduce manual work.

The following issues are some examples of what the tool can take care of:
#183
#182
#179

Proposed solution

There could be a tool that reads the generated SVG, reviews the structure and modifies the file according to some requirements we establish so the contributors won't have to manually modify inside the file.

Thanks for making a note of this. It would be cool if

• Contributions are only for the icon in a new directory like app/assets/svg/payment_icons
• We put the border path and background-color ourselves in a build tool, and generate a new icon for app/assets/images/payment_icons
• Contributors could specify the background (if they don't want white) in a separate place like payment_icons.yml

So American express entry becomes

  name: american_express
  label: American Express
  color: #032761
  group: credit_cards
