Bug: b/163595585
In a WebP image, it is possible to combine animation with an EXIF
orientation. While SkAndroidCodec attempts to handle orientation itself
by decoding into temporary memory and then drawing through a matrix,
this doesn't work directly when compositing a P-frame into a prior
frame. SkAnimatedImage already uses an SkMatrix to handle cropping and
scaling, so update that matrix to include the orientation.
Make SkAnimatedImage a friend of SkAndroidCodec. This allows the former
to have the same ExifOrientationBehavior specified by the latter, and to
recreate the latter so it does not try to handle the orientation itself.
Clip SkAnimatedImage to its bounds. Android's AnimatedImageDrawable
performs its own clip, but this makes a crop rect work for other
clients.
Update getCurrentFrame to take cropping, scaling, and orientation into
account. This method is used by CanvasKit, which does not use cropping
or scaling, but will now properly orient an animation with an EXIF
orientation.
Add a GM that exercises the various combinations of ways SkAnimatedImage
can be used:
- via newPictureSnapshot (as in Android) versus getCurrentFrame
- scaling down to a dimension that can be output from the
SkAndroidCodec, versus up, which SkAnimatedImage scales
- with a crop rect
- with a post processor

The only caller is CanvasKit, and SkAnimatedImage already has getBounds
(from SkDrawable) which does the same thing, except it returns
SkScalars. It also takes scaling and cropping into account, which
CanvasKit does not use, and in a future commit, it will consider
orientation. Switch CanvasKit to use getBounds.

Expose a android framework-only function to reset the saved clip geometry
a device-space pixel rect (e.g. the device clip restriction). Using a
regular intersect clip operation after this call should match the
behavior of the legacy replace operation with a clip restriction.
This is a step to removing the separate device clip
restriction API and the deprecated expanding clip ops, as part of the
plan described here: https://docs.google.com/document/d/1ddIk74A1rL5Kj5kGcnInOYKVAXs3J2IsSgU5BLit0Ng/edit?usp=sharing

This will make it clear that these files are for Android use and
avoid compiling them for other clients.
Update testing tools to use android::skia::BitmapRegionDecoder, but
only if SK_ENABLE_ANDROID_UTILS is defined.
Take this opportunity to clean up the class:
- The base class, which was originally designed to allow switching
amongst different implementations, is no longer needed. Rename
SkBitmapRegionCodec to android::skia::BitmapRegionDecoder
(following the new convention and matching the Java API name).
Continue to inherit from SkBitmapRegionDecoder temporarily, to
allow Android to switch to the new API.
- Use std::unique_ptr instead of passing raw pointers.
Add a test to verify that we only create a BitmapRegionDecoder if
it is one of the supported types.

Flutter on the web wants to be able to extract arbitrary frames from
an animated image and pass those into functions like:
drawAtlas, drawImage, drawImageRect
This should allow that to happen w/o having to add lots of variants like
drawAnimatedImage. If this sticks, is drawAnimatedImage still useful?
(maybe it saves a copy?)

Bug: 78866720
The client in Android calls newPictureSnapshot, which results in copying
the mutable SkBitmap into a newly allocated one in each frame. Avoid
this by calling SkMakeImageFromRasterBitmap with
kNever_SkCopyPixelsMode. Make SkAnimatedImage copy on write, by copying
before decoding if the bitmap's pixel ref is not unique.
Android's AnimatedImageDrawable's current architecture only decodes one
frame in advance, so it will never need to perform the copy on write.
This will save one bitmap allocation per GIF frame.
Add a test to verify that copy on write works as expected.
