* Add block drag surface translateSurfaceBy * Add dragged connection manager * Add gesture.js * Add GestureHandler * Implemented gesture skeleton * Most basic workspace dragging * Add dragged connection manager * cleanup * doc * more cleanup * Add gesture handler * Add translateSurfaceInternal * core/block_dragger.js * cleanup * Pull in changes to dragged connection manager * Pull in changes to dragged connection manager * comments * more annotations * Add workspace dragger * Add coordinate annotations * Start on block dragging * Limit number of concurrent gestures * Add some TODOs * start using dragged connection manager * Set origin correctly for dragging blocks * Connect or delete at the end of a block drag. * cleanup * handle field clicks and block + workspace right-clicks * move code into BlockDragger class, but still reach into Gesture internals a lot * Clean up block dragger * Call blockDragger constructor with correct arguments * Enable block dragging in a mutator workspace * Add workspace dragger * click todos * Drag flyout with background * more dragging from flyout * nit * fix dragging from flyouts * Remove unused code and rename gestureHandler to gestureDB * Rename gesture handler * Added some jsdoc in gesture.js * Update some docs * Move some code to block_svg and clean up code * Lots of coordinate annotations * Fix block dragging when zoomed. * Remove built files from branch * More dragging work (#1026) -- 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 * Fix events in new dragging (#1060) * rebuild for testing * 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.
