Patch by Arvid Nilsson <anilsson@rim.com> on 2012-05-28
Reviewed by Rob Buis.

Source/WebCore:

The new API allows the embedder to specify the root transform and many
OpenGL related parameters.

Also refactor the code to allow several sets of layers to be rendered,
and to allow interleaving the rendering of layers with rendering of
buffers and checkerboard.

Source/WebKit/blackberry:

The new API allows the embedder to specify the root transform and many
OpenGL related parameters to be used when rendering the web page.

To honor the transform, we have to implement a way to composite the
BackingStore output using a generic transform. This method,
BackingStorePrivate::compositeContents(), uses a strategy that differs
from blitContents(), because that one is optimized for software
blitting, while this one is optimized for GPU rendering. Specifically,
instead of drawing the checkerboard first, and the rendered subregions
of the tile afterward, we draw the whole tile in one call, and then
draw checkered regions on top, if any.

Removed the blit generation condvar from the new code paths for drawing
BackingStore output using a transform, since the condvar is ineffective
in preventing flicker when we're not in charge of swapping the window.
Instead, another synchronization solution will be implemented in the
future.
