Improve performance of block dragging. This is a backport of the block drag surface from scratch-blocks. At the beginning of a block drag, blocks get moved to a drag surface which then translates using translate3d to avoid repainting the entire svg on every mouse move. At the end of the drag, the blocks are dropped back in the svg in their new position.
* Record whether the workspace has been dragged
This fixes#473 by differentiating between a touch on an unmovable block
and using it to drag the workspace.
* Remove isScrolling and add DRAG_BEGIN
Applied after PR review.
* Add a new method to be called when the contents of the workspace change and
the scrollbars need to be adjusted but the the chrome (trash, toolbox, etc)
are expected to stay in the same place.
Change a bunch of calls to svgResize to either be removed or call the new
method instead. This is a nice performance win since the offsetHeight/Width
call in svgResize can be expensive, especially when called as often as we do -
there was some layout thrashing.
This also paves the way for moving calls to recordDeleteAreas
(which is also expensive) to a more cacheable spot than on every
mouse down/touch event.
of things (namely the scrollbars)
* Fix size of graph demo when it first loads by calling svgResize.
The graph starts with fixed width and was relying on a resize event
to fire (which I believe was removed in commit
217c681b86).
* Fix the resizing of the code demo. The demo's tab min-width used to
match the toolbox's width was only being set on a resize event, but
commit 217c681b86 changed how that worked.
* Fix up some comments.
* Use specific workspaces rather than Blockly.getMainWorkspace().
* Make workspace required for resizeSvgContents and update
some calls to send real workspaces rather than ones that are
null.
Remove the private tag on terminateDrag_ because it is only
actually called from outside the BlockSvg object.
* Remove a rogue period.
* Recategorize BlockSvg.terminateDrag_ to @package instead of @private so that
other developers don't use it, but it still can be used by other Blockly classes.
* Add a TODO to fix issue #307.
* Add @package to workspace resizeContents.
