This fixes a bug where Modeling#updateLabel would not work on
text annotations, because these need to have labels pre-configured.
* Modeling#updateLabel now takes the (optional) newBounds
* newBounds must now explicitly be passed to trigger resize
for text annotations
* newBounds is _only_ passed for text annotations via
LabelEditingProvider (it was discarded before anyway)
* lib/features/label-editing did not depend on lib/features/modeling
for historical reasons. It now uses the offical #updateLabel
API provided by Modeling
* Localize test diagrams
Closes#753
* take target attach and parent hints on `connection.create`
rule into account to implement create from context-menu
Related to bpmn-io/diagram-js#242
Closes#742
Add basic auto-placement of boundary events:
* handle top aligned events
* handle bottom aligned events
* take boundary events into account when placing
host elements and vice versa
Related to #563
Elements will automatically be created at appropriate
positions when context menu create entries are being
clicked (rather than dragged).
This marks a major step forward for mobile modeling,
too as dragging, especially dragging out from very small
controls is very cumbersome to do.
Things we take into account:
* for bpmn:FlowNodes, we try to compute the current
distance between elements on the flow based on
connections going in and out of the flow nodes
source element
* for bpmn:TextAnnotation we assume placement of the
element top right of the source shape
* for bpmn:DataObject and friends we assume a
placement bottom right of the source shape
* for all elements, we try not to place elements on
top of each other; i.e. new elements will be pushed
up or down accordingly, if an element at a chosen
position does already exist
Integration into other services:
* context pad provider works with autoPlace, if
available and defaults to drag start without
* auto placed elements are selected and direct editing
may conditionally be activated based on element type
(LabelEditingProvider knows the rules)
Users can out out of autoPlace by specifying the configuration
property `config.contextPad.autoPlace = false`.
Closes#563
BREAKING CHANGE:
* This breaks the default interaction from the context
pad; if you rely on clicking to start the drag
you can opt out of autoPlace:
```
new BpmnJS({ contextPad: { autoPlace: false } });
```
* ordering provider ensures sequence flows appear
behind tasks
* importer makes sure we render elements in the order
lanes > sequence flows > other flow elements
* consistent minimal opacity ensures elements in
front of tasks don't look _connected_
Closes#727
