//   "src_height" can be negative indicating a vertically flipped image source.
// "crop_width" / "crop_height" is the size to crop the src to.
//    Must be less than or equal to src_width/src_height
//    Cropping parameters are pre-rotation.
// "rotation" can be 0, 90, 180 or 270.
// "fourcc" is a fourcc. ie 'I420', 'YUY2'
// Returns 0 for successful; -1 for invalid parameter. Non-zero for failure.
