GPU canvas optimizations

[webkit] HTML5 canvas recording rendering optimization.

Currently, the canvas is being rendered on the WebCore thread into a
buffer that uses the default screen dimensions for calculating its
size. The reason is that the true screen dimensions aren't known
until we reach the UI thread in preparation for rendering
to the screen. To avoid creating canvas buffers that are larger than
necessary and require scaling before being composited, we convert the
canvas buffer into a SkPicture that gets played back on the UI thread.
We only enable the recording canvas for animations and we convert back
to a bitmap when necessary (pixel readbacks, etc)

Allows for turning on/off recording canvas through a property

Change Skpicture xfer mechanism for gpu canvas

Change the mechanism of transfer of SkPictures from layers to directly
using maps. In the old mechanism, the layers would get queued up and
dropped if the texture generation thread could not update its rendering
fast enough. This would lead to jerky visuals due to dropped frames
despite high rendering fps. In the new mechanism, through
synchronization between the webcore and the UI thread, the latest frame
for a canvas will get displayed regardless of the layer being used.

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.

        Verified new tests in WebKit and Chromium. Skipped tests on

Bug fixes for gpu canvas

Revert changes for guimark3 fps banner
Fix bug due to incorret lifecycles of the gpu canvas object, where it
was getting deleted in the webcore thread and could potentially get
accessed in the UI thread for a couple of frames before the swap could
clear out old layer. This could cause UI thread to block while trying
to lock a non-existing object or potentially cause corruption.
Changed the creation and destruction of the gpu canvas object to the
canvas layer itself so that the lifecycle can be handled better and
protected using mutexes.

Recording canvas bug fix

There is a bug due to which skpicture can be used at non frame boundaries.
The resulting skpicture that is converted to playback mode may be accessed by
javascript to record onto it, and causing a crash. The code using skpicture
now only accesses it at frame boundaries.
