Engine: Refactored SystemGraphic transparency

Previously, every time a transparent section of SystemGraphic had to be rendered, it would be to be fed through Toolkit, FilteredImageSource, TransparentImageFilter and converted from a BufferedImage to an Image to a BufferedImage again. This has been replaced (and optimized) by preforming this when the SystemGraphic is loaded into memory, instead of every time it is used.
