If a frame does not have a valid transparent index and it covers the
prior frame, it does not really depend on that frame. Instead, it
depends on the frame that the prior frame depends on.
Determine this once we have parsed the local color map (if any), so a
transparent index out of range of the color map is not considered
valid.
Share code that determines whether a frame has a transparent pixel.
Add a test that we compute the dependencies correctly. randPixelsAnim.gif
has 13 frames. After the first, the frames cover all combinations of
- Whether the prior frame was keep, restoreBG or restoreToPrevious
- Whether the new frame covers the prior frame
- Whether the new frame has a transparent pixel
(It only does so when using a global color table. It may make sense to
expand the test to also cover using local color tables.)
The test caught a bug where we incorrectly reused an existing
SkColorTable for a different frame. Fix that bug by keeping track of
the transparent index associated with the current SkColorTable.

In SkBmpCodec, if the header size does not match a known header,
stop trying to create an SkCodec. We do not know of any BMPs with
arbitrarily sized headers, so this should not cause any real
regressions.
In addition, this fixes a bug where we attempt to read too much data
from a file. Since we attempt to read the header size in one read,
and a size reported by the "BMP" may be larger than SSIZE_MAX, this
will crash when reading from a file.

Prior to this CL, if a GIF file was truncated before reading the local
color map of a frame, incremental decode would do the wrong thing. In
onStartIncrementalDecode, we would either create a color table based on
the global color map, or we would create a dummy one with only one
color (transparent). The dummy color table is correct if there is
neither a global nor a local color map, and allows us to fill the frame
with transparent. But if more data is provided, and it includes an
actual color map and image data, one of the following can happen:
- If the created color table is smaller than the actual one, the
decoded data may include indices outside of the range of the created
color table, resulting in a crash.
- If we get lucky, and the created color table is large enough, it may
still be the wrong colors (and most likely is).
To solve this, make onStartIncrementalDecode fail if there is a local
color map that has not been read yet. A future call may read more data
and read the correct color map.
This is done by returning kIncompleteInput in
SkGifCodec::prepareToDecode if there is a local color map that has not
yet been read. (It is possible that there is no color map at all, in
which case we still need to support decoding that frame. Skip
attempting to decode in that case.)
In onGetPixels, if prepareToDecode returned kIncompleteInput, return
kInvalidInput. Although the input is technically incomplete, no future
call will provide more data (unlike in incremental decoding), and there
is nothing interesting for the client to draw. This also prevents
SkCodec from attempting to fill the data with an SkSwizzler, which has
not been created. (An alternative solution would be create the dummy
color table and an SkSwizzler, which would keep the current behavior.
But I think the new behavior of returning kInvalidInput makes more
sense.)
Add tests to verify the intended behavior:
- getPixels fails.
- startIncrementalDecode fails, but after providing more data it will
succeed and incremental decoding matches the image decoded from the
full stream.
- Both succeed if there is no color table at all.
