Open the kimono a bit further with regard to images.

Games can obtain the internal platform image object, and can also construct new
per-backend images from an internal platform image object. The methods in
question are:

JavaImage.bitmapImage()
AndroidImage.bitmap()
HtmlImage.imageElement()
IOSImage.cgImage() (note that toUIImage() is already available and useful)
FlashImage.bitmapData()
Open the kimono with regard to sounds.

Added methods for creating sounds based on low-level platform sources. For Java
this means an InputStream, for Flash, HTML and iOS this means a URL (which in
the case of iOS can be a file: URL), for Android this means a FileDescriptor or
an AssetFileDescriptor.

Go crazy.
