* Fix wrong width of field_dropdown with an image on Edge / IE
* Avoid re-rendering on IE and Edge by using getBBox().width to compute the text width on those browsers
* 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.
