* Create a generator that uses the Android NDK's APIs for decoding images.
*
* Only supported on devices where __ANDROID_API__ >= 30.
*
* As with SkCodec, the SkColorSpace passed to getPixels() determines the
* type of color space transformations to apply. A null SkColorSpace means to
* apply none.
*
* A note on scaling: Calling getPixels() on the resulting SkImageGenerator
* with dimensions that do not match getInfo() requests a scale. For WebP
* files, dimensions smaller than those of getInfo are supported. For Jpeg
* files, dimensions of 1/2, 1/4, and 1/8 are supported. TODO: Provide an
* API like SkCodecImageGenerator::getScaledDimensions() to report which
* dimensions are supported?
