[chromium] Implement deferred image decoding
https://bugs.webkit.org/show_bug.cgi?id=94240

Reviewed by Stephen White.

Source/WebCore:

Objectives:

To record image decoding operations during painting and to defer
decoding operations until rasterization.

Rationale:

This is a key feature that enables impl-side painting which requires
fast recording of drawing operations. The existing decode-on-draw
restricts that recording has to block on expensive decoding operations.
This change allows recording of image decoding operations during paint
time.

Design:

Image decoding happens when a BitmapImage is drawn into a
GraphicsContext. When per-tile painting is enabled GraphicsContext
is backed by SkCanvas in recording mode. This SkCanvas records drawing
and image decoding operations to minimize recording time.

An image decoding operation is recorded as a SkPixelRef object
implemented by LazyDecodingPixelRef. This object references raw encoded
data, regions to be decoded and scaling information.

When used in conjunction with per-tile painting this feature defers
image decoding until the SkCanvas referencing the image is rasterized.

Both recording and rasterization happen on the main thread.

Performance Impact:

This feature is enabled by WebKit::setDeferredImageDecodingEnabled()
and does not have an impact when disabled.

This feature is disabled by default.

Upcoming Changes:

1. Implement a full-featured image cache in ImageDecodingStore.
2. Allow rasterization and decoding on impl thread.

Classes Involved:

BitmapImage

BitmapImage is the entry point for deferred image decoding. When
drawing a BitmapImage into a GraphicsContext it makes a request to
create a NativeImageSkia. We substitute the content in NativeImageSkia
such that it is lazily decoded.

DeferredImageDecoder

This is the platform implementation of a image decoder for Chromium.
This is a bridge layer that either delegates calls to the actual
ImageDecoder or create a lazily-decoded SkBitmap and delegates calls
to ImageDecodingStore.

ImageDecodingStore

This object manages all encoded images. It keeps track of encoded
data and the corresponding ImageDecoder for doing actual decoding. It
is also responsible for generating lazily decoded SkBitmaps. This
SkBitmap contains a LazyDecodingPixelRef object which references to an
image entry in ImageDecodingStore.

ScaledImageFragment

A container for a scaled image fragment. In addition to bitmap pixels
it contains information about the ID of the image, scale and clipping.

ImageFrameGenerator

This object is responsible for generating decoded pixels. It is also
a container for encoded image data and corresponding image decoder.

LazyDecodingPixelRef

This object is embedded in a SkBitmap to enable lazy decoding. When
SkBitmap needs to access pixels LazyDecodingPixelRef is locked. It
contains information to locate an image and scaling info, these
information is submitted to ImageDecodingStore to access actual pixels.

Layout tests. There are about 80 tests in this virtual test suite
running this feature in this directory:

platform/chromium/virtual/deferred/fast/images

Unit tests. Added DeferredImageDecoderTest to verify deferred
image decoding behavior.

Shader translator needs option to clamp uniform array accesses in vertex shaders
https://bugs.webkit.org/show_bug.cgi?id=98977
https://code.google.com/p/angleproject/issues/detail?id=49

Reviewed by Alok Priyadarshi and Ken Russell.

Source/ThirdParty/ANGLE:

WebGL does not allow GLSL code to index a uniform array outside its bounds. Add a
flag to the ANGLE compiler to insert clamp statements around such indexing.
Since it is possible to access vec2/3/4 and mat2/3/4 components by array indexing,
they must be similarly clamped.

Unfortunately, it is currently not possible to always determine that the indexing is
operating on a uniform variable. For example, suppose we have "uniform mat4 a". ANGLE
is currently not able to tell us that the rvalue of "a[0]" is a uniform, just that
it has a size of 4. Therefore, the clamping is done on all indirect array indexing.

This will have a performance impact. Future enhancements may be able to determine
cases where the clamping is not necessary. Currently only direct indexing is skipped
(i.e. looking up a value using a constant index).

The clamp insertion is only performed on the GLSL output. Direct3D already guarantees
that out-of-bounds uniform array access returns a zero value.

Source/WTF: 

Disabled by default. Should have no performance and memory cost when
disabled. To enable, #define ENABLE_STACK_STATS 1 in StackStats.h.
The output is currently hardcoded to be dumped in /tmp/stack-stats.log,
and is in the form of stack sample events. By default, it only logs
a sample event when a new high watermark value is encountered.

Also renamed StackBounds::recursiveCheck() to isSafeToRecurse().

We should limit the tile cache coverage when a page can't take 
advantage of fast tile scrolling anyway

Reviewed by Simon Fraser.

When sites can't use fast-scrolling, there is no need to inflate the 
tile cache. In fact, we get a performance boost by keeping it small 
on painting-intensive sites. 

Instead of just looking a whether or not the FrameView 
canHaveScrollbar(), consult 
shouldUpdateScrollLayerPositionOnMainThread().
