Graphics.generateTexture has a new argument padding which allows you to add extra spacing onto the generated texture. This is useful for small Graphics objects where you find a few pixels getting sliced off the edges due to rounding issues (phaserjs#1933)

 * PIXI.WebGLGraphics.stencilBufferLimit is a new integer that allows you to define how many points exist in a Graphics object before Pixi swaps to using the Stencil Buffer to render it. The default is 6 but can be increased. This fixes issues with things like Quadratic curves not rendering as masks in WebGL.
 * If a Display Object with a mask contained a child with a Filter, then the child would not render. The WebGLFilterManager now retains state and creates a new stencil buffer as required (thanks @hightopo #1842)
 * The Filter Texture and GL Viewport are now properly resized, fixing issues with custom resolutions and filters (thanks @englercj @amadeus #2326 #2320)
