* chore: move functions from utils to more specific files
* chore: use new names for utils functions
* chore: run clang-format
* chore: add deprecation warnings back to utils.js
Our files are up to a decade old, and have churned so much, that the initial author of the file no longer has much meaning.
Furthermore, this will encourage developers to post to the developer group, rather than emailing Googlers (usually me) directly.
* Add annotations to files under core/events
* Add annotations to files under core/interfaces
* Add annotations to files under core/keyboard_nav
* Add annotations to files under core/renderers
* Add annotations to files under core/serialization
* Add annotations to files under core/theme
* Add annotations to files under core/toolbox
* Add annotations to files under core/utils
* Add annotations to files under core
* Migrate core/workspace_drag_surface_svg.js to ES6 const/let
* Migrate core/workspace_drag_surface_svg.js to goog.module
* Migrate core/workspace_drag_surface_svg.js to named requires
* clang-format core/workspace_drag_surface_svg.js
* Re-wrap strings onto one line
* 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.
* Fix#1275 by adding a more specific rule for overflow:visible on the drag surface svg. This wins out over a common bootstrap rule that says: svg:not(:root) {overflow:hidden} and helps avoid a difficult problem for Blockly users to diagnose.
* Update css.js
* Change the setting of the CSS transform properties on SVG nodes to set both the unprefixed version and the `-webkit-` prefixed version so that Blockly correctly renders in order browsers, such as Safari < 9 and iOS Safari < 9.2. For discussion of this issue, see https://groups.google.com/forum/#!topic/blockly/o3pERaRQhSg
* Correct the separation between the CSS transform property and the rest of the CSS that was in the variable misleadingly called "transform".
* Add a workspace drag surface that blocks and bubble get moved to during a workspace drag.
The surface is translated using translate3d instead of svg's translate attribute so that
the browser does not have to repaint the entire workspace on every mouse move.
This is very similar to the block drag surface.
* Address code review comments
* add back hasClass_ utility removed in #748 and stop using contains since it is not supported in IE
