Timo Tijhof 14343c7bf7 ve.ui.Toolbar: Refactor floating logic for performance
== Renamed methods ==

* enableFloating  -> enableFloatable
* disableFloating -> disableFloatable
* setPosition     -> float
* resetPosition   -> unfloat

== Scroll and resize event ==

Timeline for scroll event reduced from about half a dozen
"Recalculate style" and various forced "Paint" down to 0.

New timeline for scroll is clean (for me: from ~35 to ~59 fps):
* 1 Event (scroll)
* 1 Composite Layer

The composite layer action is the browser changing the viewport
to a different portion of the document drawing. Exactly the one
thing a simple scroll should do.

Timeline for resize event is still pretty crowded and low fps,
but it has improved. Further improvement would likely be around
using requestAnimation and going outside ve.ui.Toolbar.

== Changes ==

* New: ve.ui.Toolbar#initialize.
  Similar to what surface has. Users of Toolbar should decide
  whether to call enableFloatable, append it to the DOM at some
  point and then call initialize() once.

* Don't compute offset() every time.
  Eliminated by doing it once in #initialize. These 'top' and
  'left' offsets do not change.

* Don't compute outerWidth() and $window.width() every time.
  Reduced by doing it once in #initialize to compute the 'right'
  offset. Updating it only on resize.

* Don't set 'top' every time.
  This is already in the stylesheet. It was never set to anything
  else so the abstraction for it in #float has been removed.
  This also made it obvious that code for "ve-ui-toolbar-bottom"
  was unused and left behind. Tha class was only ever being
  removed from something (never added).
  The one addClass call for it was in a condition that is always
  false ("if top > 0").

* Don't set 'left' every time.
  Eliminated by doing it once in #float.

* Don't set 'right' every time.
  Reduced by no longer doing it on scroll. Done once in #float,
  and on resize after computing the new value for it.

* Remove no-op style operations.
  Wrapped methods in if-floatable, if-floated etc. to reduce a
  fair amount of easily avoided re-paint overhead.

* Avoid double re-paint in mw.ViewPageTarget.
  Though we prevent a lot of redundant re-paints now, whenever
  we do repaint we want to do it in 1 repaint instead of 2.

  ve.ui.Toolbar emits #toolbarPosition, which tells
  mw.ViewPageTarget to update toolbarTracker which would read
  the new $bar style properties and copy them over to the
  $toolbarTracker. However, this read operation forces the browser
  to do an immediate re-paint half-way just for $bar.

  Browsers only repaint when style properties are changed and
  JS has yielded. The exception to this is JS reading style
  properties: in that case the browser is forced to do those
  deferred repaints directly and reflect the new values.

  We can avoid this double repaint by passing the updated values
  as data instead of requiring the receiver to read the DOM (and
  thus a keep the deferred repaint). Now toolbarTracker can use
  them directly whilst the browser hasn't even repainted $bar yet.

== Clean up ==

* Redundant "border-radius: 0". This would reset something, but
  it never does. None of the things it inherits from set a
  border-radius. There is one subclass where toolbar is used
  with a border-radius (".ve-ui-surfaceWidget .ve-ui-toolbar-bar"
  sets a border-radius) which overrides this on purpose, so the
  default of 0 is redundant.

* Pattern "if ( .. ) addClass() else removeClass()" changed to:
  "toggleClass( , .. )"

Trevor Parscal 2e76271b4e The Great ve.ui.Surface refactor of 2013
Prologue:

Farewell ve.Editor my good chap… Oh, hey there HTML frames - I didn't
see you there! In a world where iframes are outlaws, and symbols like
document and window are global, there were more than a few assumptions
about which document or window was being used. But fear not - for this
commit (probably) tracks them all down, leaving a trail of
iframe-compatible awesomeness in its wake. With the great ve.ui.Surface
now able to be used inside of iframes, let the reference editing
commence. But there, lurking in the darkness is a DM issue so fierce it
may take Roan and/or Ed up to 3 whole hours to sort it out.

Note to Roan and/or Ed:

Editing references seems to work fine, but when saving the page there
are "no changes" which is a reasonable indication to the contrary.

Objectives:

* Make it possible to have multiple surfaces be instantiated, get along
  nicely, and be embedded inside of iframes if needed.
* Make reference content editable within a dialog

Approach:

* Move what's left of ve.Editor to ve.ui.Surface and essentially
  obliterate all use of it
* Make even more stuff inherit from ve.Element (long live this.$$)
* Use the correct document or window anywhere it was being assumed to be
  the top level one
* Resolve stacking order issues by removing the excessive use of z-index
  and introducing global and local overlay elements for each editor
* Add a surface to the reference dialog, load up the reference contents
  and save them back on apply
* Actually destroy what we create in ce and ui surfaces
* Add recursive frame offset calculation method to ve.Element
* Moved ve.ce.Surface's getSelectionRect method to the prototype

Bonus:

* Move ve.ce.DocumentNode.css contents to ve.ce.Node.css (not sure why it
  was separate in the first place, but I'm likely the one to blame)
* Fix blatant lies in documentation
* Whitespace cleanup here and there
* Get rid of ve.ui.Window overlays - not used or needed

Trevor Parscal a56e795f58 ve.Editor
Objectives:

* Split ve.Surface into ve.Editor and ve.ui.Surface
* Move actions, triggers and commands to ve.ui
* Move toolbar wrapping, floating, shadow and actions functionality to configurable options of ve.ui.Toolbar
* Make ve.ce.Surface and ve.ui.Surface inherit ve.Element and use this.$$ for iframe friendliness
* Make the toolbar separately initialized so it's possible to have a surface without one, as well as control where the toolbar is

Some change notes:

VisualEditor.php
* Added standalone module for mediawiki integrated unit testing

ve.ce.Surface.js
* Remove requirement to pass in an attached container to construct object
* Inherit ve.Element and use this.$$ instead of $
* Make getSelectionRect iframe friendly
* Move most of the initialize stuff to a new initialize method to be called after the surface is attached to the DOM

ve.init.mw.ViewPageTarget.js
* Merge toolbar functions into setup/teardown methods
* Add toolbar manually (since it's not added by the surface anymore)

ve.init.sa.Target.js
* Update new init procedure for editor, surface and toolbar separately
* Move toolbar floating stuff to ve.Toolbar

Trevor Parscal 1572ec1569 Context, frame, window, dialog and inspector refactor
This is a major refactor of user interface context, frame, dialog
and inspector classes, including adding several new classes which
generalize managing inspectors/dialogs (which are now subclasses
of window).

New classes:
* ve.ui.Window.js - base class for inspector and dialog classes
* ve.ui.WindowSet.js - manages mutually exclusive windows, used
  by surface and context for dialogs and inspectors respectively
* ve.ui.DialogFactory - generates dialogs
* ve.ui.IconButtonWidget - used in inspector for buttons in the head

Refactored classes:
* ve.ui.Context - moved inspector management to window set
* ve.ui.Frame - made iframes initialize asynchronously
* ve.ui.Dialog and ve.ui.Inspector - moved initialization to async
  initialize method

Other interesting bits:

ve.ui.*Icons*.css, *.svg, *.png, *.ai
* Merged icon stylesheets so all icons are available inside windows
* Renamed inspector icon to window

ve.ui.*.css
* Reorganized styles so that different windows can include only
  what they need
* Moved things to where they belonged (some things were in strange places)

ve.init.Target.js, ve.init.mw.ViewPageTarget.js, ve.init.sa.Target.js
* Removed dialog management - dialogs are managed by the surface now

ve.ui.*Dialog.js
* Renamed title message static property
* Added registration

ve.ui.*Inspector.js
* Switch to accept surface object rather than context, which conforms
  to the more general window class without losing any functionality
  (in fact, most of the time the surface was what we actually wanted)

ve.ui.MenuWidget.js, ve.ui.MWLinkTargetInputWidget.js
* Using surface overly rather than passing an overlay around
  through constructors
