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 Change-Id: Iede83e7d24f7cb249b6ba3dc45d770445b862e08
