graphics API based on OpenGL ES 2.0 to JavaScript. WebGL is not compiled
by default. It can be enabled by setting ENABLE_WEBGL = true in your
device BoardConfig.mk or directly in external/webkit/Android.mk.
Includes runtime enablement through Browser Settings -> Labs menu.
Enable WebGL debug logs and FPS timing with: adb shell setprop debug.webgl 1
Includes Cross-origin resource sharing support.

Factor CORS request preparation out of DocumentThreadableLoader
https://bugs.webkit.org/show_bug.cgi?id=61209
DocumentThreadableLoader has two jobs:
1) Proxy loads between threads.
2) Run the CORS state machine.
This patch begins the work of separating those concerns, allowing CORS
to be used elsewhere in the loading pipeline. In particular, this
patch moves knowledge of how to prepare CORS requests out of
DocumentThreadableLoder.

Make CachedResource take a ResourceRequest instead of just a url string.
2011-05-24 Nate Chapin <japhet@chromium.org>
Reviewed by Adam Barth.
Change CachedResources to take a ResourceRequest instead of
a url in their constructors and provide a very minimal set of
cases for avoiding reusing a CachedResource. The ResourceRequest
part of this change requires pushing responsibility
for calling Document::completeURL() to the caller, instead of
CachedResourceLoader, since ResourceRequest ASSERTs if it
is constructed with an invalid url.

Clear the composited mode for layers before running the loop to mark the
ones following a fixed layer as composited. This fixes the scenario
where a layer switches between fixed and not, but the layers following
it have an inconsistent compositing mode.

Don't enable composited layers for fixed elements with a width or height
of 1 or less. This duplicates the check used for deciding if layers
following fixed layers are composited or not.
This fixes the scenario where updateBacking() switches composited mode
on (by calling enableCompositingMode()) because a layer is fixed, while
computeCompositingRequirements() will disable it, and results in a
segfault in updateCompositingLayers()

- Promote absolute positioned elements to be composited
- Reorder the elements as needed in LayerAndroid
- Simplify fixed elements composition culling (don't do it anymore,
we just promote everything and let the Layers sort things out)

Merge multiple painted layers into a LayerGroup to share a dualTiledTexture

This drastically improves performances, as invalidating a canvas
will only touch that one layer instead of (possibly) invalidating the
entire PictureSet.

We normally do not necessarily promote fixed or scrollable
elements to compositing layers to try and reduce the number
of layers that get created. However in the case that such
an element appears in the negative z-order, we must do
the promotion to ensure that the layer is painted at the
correct z-index in the hierarchy (i.e not too high - sites
like to use a fixed image with z-index:-1 to implement
a fixed background -- without this patch we end up painting
the background over the main page content).

- overflow elements triggered all layers before them to be composited;
this is not needed at all...
- fixed elements will trigger layers after them to be composited, but
we don't need to composite all of them -- the one fully contained
into previous composited layers don't need to...

This lets the GraphicsLayerClient instance decides whether it has
owning RenderLayer, instead of using static_cast.
This makes overflow'ed iframe scrollable again.
This change also reverts Tenghui's CL:
https://android-git.corp.google.com/g/#change,115508
Tested on scrollable iframe and inline video.

We used to rely on the fact that RenderLayerBacking is the only subclass of
GraphicsLayerClient, but now the RenderLayerCompositor also inherit it and
is used for iframe. That cause us to get invalid pointer in GraphicsLayerAndroid.
The solution here is to disable the new webkit approach b/c we have our own
iframe support already.

iframe compositing propogation now works for <object> and framesets so
the methods have been renamed - implement that renaming in our code.
