* Google changed from an Inc to an LLC.
This happened back in 2017 but we didn’t notice. Officially we should update files from Inc to LLC when they are changed as part of regular edits, but this is a nightmare to remember for the next decade.
* Remove project description/titles from licenses
This is no longer part of Google’s header requirements. Our existing descriptions were useless (“Visual Blocks Editor”) or grossly obselete (“Visual Blocks Language”).
* License no longer requires URL.
* Fix license regexps.
* Break CSS into modules.
Drops the compile test by 3 KB.
Remove obsolete .blocklyDraggable class stub (it used to be dynamically changed).
Remove unused menuseparator CSS.
Random improvements to require statements.
Removal of some obviously dead CSS.
.blocklyDropDownDiv no longer supresses text selection (see comment in PR).
This PR drops the compiled size by 4 KB, which is larger than I was expecting.
No Blockly instances need both Horizontal and Vertical flyouts. Dropping one of these saves 2 KB. Some don’t need flyouts at all (e.g. Blockly Games Puzzle or readonly documentation blocks).
Also removes three private accesses from workspaceSvg into toolbox tree.
The strategy for workspace.updateToolbox is no longer to clear and repopulate the toolbox, but rather to throw away the old toolbox and rebuild a new one. This is simpler and more reliable.
This commit trims off another KB from the compiled code.
1) Simplifications.
2) Enable toolbox category colours to be specified using the full range of CSS formats (not just hue or #rrggbb).
3) Fix bug where `Blockly.utils.checkMessageReferences('%{BKY_today} %{BKY_xxx}')` returns true.
Instead of top/left/height/width. Given our uses of Rect, it makes the math slightly simpler.
This is a setup for using Rect in other places. Currently it is only used to describe delete areas.
* Fix 19 warnings in theme-related code.
Resolves#2414
* Remove suppressPrefixSuffix property definition
The mixin code throws an error if property exists on both objects.
* eslint has strange ideas about indentation.
Fixes regression in #1893. Patch on change in #1831.
Verify typeof colour variable before passing through Number().
Missing attributes return null, and Number(null) === 0, resulting in a red hues category color.
