Makefile.vc still to be updated...
Meanwhile the CL environment variable can be supplemented with

f0d6a14b64 gif2webp: Insert independent frames at regular intervals. 
We use the 'do not blend' option for creating independent frames.
We also mark the already independent frames as 'do not blend'.

This bounds the maximum number of frames that need to be decoded to
decode a given frame, thus leading to a much better decoding performance.

8ba1bf61a0 Stricter check for presence of alpha when writing lossless images 
Earlier, all lossless images were assumed to contain alpha.
Now, we use the 'alpha_is_used' bit from the VP8L bitstream to determine
the
same.

Detecting an absence of alpha can sometimes lead to much more efficient
rendering, especially for animated images.

Related: refine mux code to read width/height/has_alpha information only
once
per frame/fragment. This avoid frequent calls to VP8(L)GetInfo().
