Fix overdrawing of the checkerboard layer by letting layers have a concept of
a display-port, and keeping the root layer's display port in track with
Gecko's.
Fix overdrawing of the checkerboard layer by letting layers have a concept of

Gecko's.
- Disable fps layer.
- Add some comments to FlexibleGLSurfaceView.
- Get rid of getBufferSize and some other related cleanup.
- Add some comments to compositor-invoked functions in GeckoLayerClient.
- Take out unnecessary parameters to Rect constructor.
- Move class variable initialization to constructor.
- Take out kUsingGLLayers.
- Add a comment about changes in background color.
- Fix up convertViewPointToLayerPoint to be more correct.
- Add note in setPositionAndResolution about how it might be wrong.
- Modify provideEGLSurface to not store the surface in mEGLSurface.
- Remove some unneeded, commented out code in GLThread.
Not only does this reduce the amount of cruft needed while getting and setting these properties, it
makes the code more consistent because we don't have half of this stored in the Layer base class and
the other half provided by an abstract method implementation in subclasses. Furthermore, this
allows the VirtualLayer size to be updated based on the area painted by gecko rather than remaining
fixed at the view size when the virtual layer was created.
This reduces the paint rate on things like runfield
so that we only paint at the rate that we're invalidating.
We do so by not requesting render in endTransaction
It looks like endTransaction is only called by endDrawing
on the gecko thread and only on VirtualLayers. We don't
need the extra requestRender call because we've already
done the rendering.
Only update tiles that intersect with the screen, and asynchronously update
invisible tiles over multiple subsequent frames. This has the effect of
spreading out non-critical texture-upload over time and removes some juddering
on devices that don't support gralloc.
This backs out changes d8fc13006aa4, ddde7a49f6f7, 34b1cc9454d2 and
8919c54229e1, leaving in some initialisation fixes that were introduced when
rebasing.
This work may be re-applied at a later date.
This adds checkerboard profiling to LayerRenderer, that can be enabled either
by enabling debug logging of the "GeckoLayerRendererProf" tag, or via
reflection using PanningPerfAPI.
Instead of tying the tile-buffer in MultiTileLayer directly to the back-buffer
of the page, make sure rendering is always aligned to the tile grid and use
tiles on-demand. This makes better use of tiles when panning/zooming, and opens
up the route for further optimisations.

This removes the hard-coded limit of 1024x2048 tile sizes, and allows for
arbitrary tile-sizes. It will still only allocate texture sizes in powers of
two, however. It replaces the tile size with a buffered-area size, which can be
re-allocated as the screen dimensions change.

Scrollbars now have rounded endcaps, are a little smaller, and there
is a 1-pixel gap between the bar and the edge of the viewport. Just
generally making them look nicer.
Set the render mode to RENDERMODE_WHEN_DIRTY and request a redraw when a layer
transaction ends and when the viewport in LayerController changes. This stops
us from drawing continuously.
This patch reinstates pinch-zooming and adds CSS re-scaling so that after
zooming, the page is rendered at the scaled resolution and you get clear text.
This patch refactors the code to make some of the value names and ownership
clearer, and to add the idea of a 'viewport' within a 'displayport'. The
displayport is the area of the page which is visible to the underlying buffer
and the viewport is the area of the page which is visible through the
application window.
