* The `Graphics.strokeRoundedRect` and `fillRoundedRect` methods can now accept negative values for the corner radius settings, in which case a concave corner is drawn instead (thanks @rexrainbow)
* Earcut has been updated to version 2.2.4. This release improves performance by 10-15% and fixes 2 rare race conditions that could leave to infinite loops. Earcut is used internally by Graphics and Shape game objects when triangulating polygons for complex shapes.
*`Graphics.strokeRoundedRect` would incorrectly draw the rectangle if you passed in a radius greater than half of the smaller side. This is now clamped internally (thanks @temajm)
