Increase block border/stroke width

[syvb]

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

I want to have thicker block borders, but there isn't a way I can customize them

Describe the solution you'd like

Blockly.BlockSvg.BLOCK_BORDER_SIZE = "5px"; // or any other CSS unit (e.g. em, ex, cm, %)

Describe alternatives you've considered

Blockly.BlockSvg.BLOCK_BORDER_SIZE = "5px";
Blockly.BLOCK_BORDER_SIZE = "5px";

Or perhaps this could be an option that can be included in themes.

This won't just be a single constant, because the size of the border impacts things like the spacing between blocks and the relative size of previous and next connections.

A change from 1px to 2px may be fine, while a change from 1px to 5px would probably look wrong. That said, you can follow the steps in the custom renderer codelab to modify constants and see if you like the results.
