Hey looks good for now. I think you got the basics of Cython right. What would be your next steps?

Is there anything that I could improve?

What would be your next steps?

I'll try to make the additional optimizations

@fabiobarkoski I think from a perspective of cythonization of the members and variables, the code is already pretty optimized. We now can only gain more speed with design changes to the code.

I think that this idea from the issue might be worth a try:

Currently pack() gets passed a list of frame objects, but technically only width, height and index of a frame are needed.

The idea here being is that pack doesn't get a list of TextureImage (i.e. members named block in the code) but a list that only contains a tuple of (width, height) and then only operates on that. This would also require that we use the block index in self.mapping instead of hashing the block itself.

cythonized more the texture packing, also changed the
list passed to factor(), before was a list of frame objects, now
a list of only width, height and index of the frames.
