-- Drag bubbles while dragging blocks
-- Use bindEventWithChecks to work in touch on Android. Not tested anywhere else yet.
-- Handle dragging blocks while zoomed
-- Handle dragging blocks in mutators
-- Handle right-clicks (I hope)
-- Removed lots of unused code
* More dragging work (#1048)
- Removed gestureDB
- Removing uses of terminateDrag
- Cleaned up disposal code
* Dragging bugfixes (#1058)
- Get rid of flyout.dragMode_ and blockly.dragMode_
- Make drags from the flyout start from the top block in the group
- Block tooltips from being scheduled or shown during gestures
- Don't resize mutator bubbles mid-drag

* unbuild
* Fix events
* rebuild
* Fix up cursors
* Use language files from develop
* Remove handled TODOS
* attempt to fix IE rerendering bug, and recalculate workspace positions on scroll
* Rebuild all the things
* Comment cleanup; annotations; delete unused variables.
* Change how blockly handles cursors. The old way was quite slow because it changed the stylesheet directly. See issue #981 for more details on implementation and tradeoffs. This changes makes the following high level changes: deprecate Blockly.Css.setCursor, use built in open and closed hand cursor instead of custom .cur files, add css to draggable objects to set the open and closed hand cursors.
* Split the scrollbar and flyout out into their own SVG elements. They
are siblings of the workpsace SVG. This paves the way to make performance
improvements to workspace dragging.
Add a isMutator member similar to isFlyout to workspace_svg so it knows whether
it is mutator or not. Allow blocks to access that property so that they can recalculate
coordinates appropriately.
Unless they could be converted to use goog.dom.TagName, in which case do
that. createDom is going to require goog.dom.TagName member as the
tagName parameter. This change prepares for that.
