* 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
* 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.
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.
* * apply bootstrap3 integration fixes
* Injection subcontainer
Include svg and div into a master container, which allow css better
positioning (overflow scrolling problem)
* * Fix toolbox positioning (rtl and ltr). Because toolbox if relative to injection div, only adjust it to left (ltr) or right (rtl) edge
* * fix style (thanks to @NeilFraser)
* * revert msg files
* 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.
