-    EncodeAlphaInternal: clear result->bw on error
-    
-    This avoids a double free should the function fail prior to
-    VP8BitWriterInit() and a previous trial result's buffer carried over.
-    Previously in ApplyFiltersAndEncode() trial.bw (with a previous
-    iteration's buffer) would be freed, followed by best.bw pointing to the
-    same buffer.
-    
-    Since:
-    187d379d add a fallback to ALPHA_NO_COMPRESSION
-    
-    In addition, check the return value of VP8BitWriterInit() in this
-    function.
-    
-    Bug: webp:603
