Part of dev-tools.

Is your feature request related to a problem? Please describe.

It's often helpful to download a screenshot of your blocks during development or debugging.

We have some code to do this in core Blockly. It's not ready to be published for users, but is ready to be used by developers.

Describe the solution you'd like

• Copy the contents of screenshot.js from the core Blockly repository
• Add a way to initialize it onto a workspace to put it in the context menu.

Desired functionality

• A context menu option on the workspace to download a screenshot of all blocks on the workspace.
• (optional) A context menu option on blocks to download a screenshot of the selected block (or block stack?)

APIs needed in core Blockly

• Possibly Proposal: Pluggable common context menu items for BlockSvg blockly#3237

Additional context

• Download screenshot option blockly#2914
• Proposal: Download block image blockly#3238
• Adding this to dev-tools doesn't remove the request to have it as a general-purpose plugin

Needs discussion

• API
• Tests

I think this is already done, in that it's part of dev-tools and in the context menu in the advanced playground automatically. The separate feature request for a standalone plugin is still open.

Please reopen if I've misunderstood the remaining work.
