* Change the setting of the CSS transform properties on SVG nodes to set both the unprefixed version and the `-webkit-` prefixed version so that Blockly correctly renders in order browsers, such as Safari < 9 and iOS Safari < 9.2. For discussion of this issue, see https://groups.google.com/forum/#!topic/blockly/o3pERaRQhSg
* Correct the separation between the CSS transform property and the rest of the CSS that was in the variable misleadingly called "transform".
Defer tooltip message string check until after load, when all Blockly.Msg should be loaded.
Avoids validation in headless mode, due to lack of document.readyState.
Moving all `math.js` definitions into a single JSON array, complete with i18n syntax for all messages, dropdowns, and tooltips.
Adding Blockly.Extensions.buildTooltipForDropdown(..) to facilitate the creation and error-checking of tooltips that update based on the value of a dropdown.
Now warn on raw string in JSON 'extensions'.
Adding support for string table lookups in dropdown field labels specified in JSON.
Adds Blockly.utils.replaceMessageReferences() method to handle string replacement without interpolation tokens. Effectively uses the same old code, now moved into tokenizeInterpolation_(), which takes a parseInterpolationTokens option.
Replaces the direct JavaScript references (not pure JSON, and thus not portable).
Demonstrating this behavior in the logic_boolean dropdown.
* 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.
* Adds message references to message string interpolation, in the form of %{BKY_STRING}.
* Re-adding CONTROLS_IFELSE block using the new syntax, referencing to CONTROL_IF equivalents.
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.
from getting selected. Use e.preventDefault instead of adding and removing
classes on mousedown and mouseup. This keeps the browser from having to
potentially recacluate style on mousedown and mouseup events.
css to mark text as unselectable instead. I can't prove this is
significantly faster with numbers since the call to setup the time out
costs ~.1ms and the call when the timer fires is ~.05. This happens on almost
every mouse event though. Plus, it seems to remove a flicker of highlighting when
frames are skipped and keeps scrolling via the scrollbar from highlighting.
