 * Scale an image using a high-quality filter.
 * Synchronously scales an image and writes the output to the destination in
 * 32-bit format. The destination must be pre-allocated by the caller.
 * Returns true if scaling was successful, and false otherwise. Currently, this
 * function is implemented using Skia. If Skia is not enabled when building,
 * calling this function will always return false.
 * This API is not currently easily hardware acceleratable. A better API might
 * take a SourceSurface and return a SourceSurface; the Direct2D backend, for
 * example, could simply set a status bit on a copy of the image, and use
 * Direct2D's high-quality scaler at draw time.
