Urvang Joshi 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().
