/**
* 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.
*
* IMPLEMTATION NOTES:
* 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.
