Graphics.drawArc would fail to draw any subsequent arcs if you set beginFill
on it after drawing the first arc.
Graphics.drawArc would only move to the center position of the first arc created and ignore any subsequent arcs. Graphics.drawArc now correctly renders multiple arcs across both WebGL and Canvas. You no longer need to specifically call moveTo to move into the correct place to draw the arc. Graphics.drawArc now bails out if the startAngle = the endAngle and/or the sweep is invalid *before* adjusting any points. Graphics.drawArc now correctly handles the fill on the CanvasRenderer if the arc is a subsequent arc and no line style is set.

* Text.lineSpacing is no longer applied to the first line of Text, which prevents text from being cut off further down the Text object.
|
||||
* If you paused a Sound object that is using audio markers and then resumed it, it wouldn't correctly calculate the resume duration - causing the sound to sometimes play into the marker that followed it (thanks @AnderbergE #1669)
|
||||
* Animation.play wouldn't correctly set the play state on the Game Objects AnimationManager causing the animation to fail to start (calling AnimationManager.play did work however), now they're both consistently working.
