* This function's sole purpose is to trick the linker into not discarding
* SkImageDecoder subclasses just because we do not directly call them.
* This is necessary in applications that will create image decoders from
* a stream.
* Call this function with an expression that evaluates to false to ensure
* that the linker includes the subclasses.
* Passing true will result in leaked objects.
