| SkEncoder.h |
A single frame to be encoded into an animated image.
If a frame does not fit in the canvas size, this is an error.
TODO(skia:13705): Add offsets when we have support for an encoder that supports using
offsets.

Selects which filtering strategies to use.
If a single filter is chosen, libpng will use that filter for every row.
If multiple filters are chosen, libpng will use a heuristic to guess which filter
will encode smallest, then apply that filter. This happens on a per row basis,
different rows can use different filters.
Using a single filter (or less filters) is typically faster. Trying all of the
filters may help minimize the output file size.
Our default value matches libpng's default.

|fCompression| determines whether we will use webp lossy or lossless compression.
|fQuality| must be in [0.0f, 100.0f].
If |fCompression| is kLossy, |fQuality| corresponds to the visual quality of the
encoding. Decreasing the quality will result in a smaller encoded image.
If |fCompression| is kLossless, |fQuality| corresponds to the amount of effort
put into the encoding. Lower values will compress faster into larger files,
while larger values will compress slower into smaller files.
This scheme is designed to match the libwebp API.
