This PR aims to fix tensorflow/tfjs#1426 and replaces #1637
After trying to implement specific webgl/cpu shaders in #1637 i realized
ImageProjectiveTransformis not available in the ops list of C API.Considering this, I've implemented it in a no-shader way, using
tf.gatherNDas the cornerstone of the implementation.This new version won't need to maintain multiple shaders but may be a little bit slower (i haven't fully tested the performance yet)
Since the implementation takes 300 lines, i have put it into a separated file required in
image_ops.ts.Please share your feedbacks and suggestions :-)
