This puts in most of the infrastructure needed to allow us to
switch between different densities at run time. The main remaining
uses of the global are to initialize the Bitmap object (not sure
what to do about that since it doesn't have anything passed in
the constructor to get this information from), and being able to
load drawables if we need a different density than what was preloaded
by zygote.

1. Make the feature opt-in (ViewGroup::layoutMode defaults to CLIP_BOUNDS) without inheritance.
2. Rename COMPONENT_BOUNDS to CLIP_BOUNDS.
3. Rename LAYOUT_BOUNDS to OPTICAL_BOUNDS.
4. Complete GridLayout implementation.
5. Change the default_gap between components to 8dp, to align with the Style Guide.

Add layout bound metadata to 9-patch files and make layouts take them into account.
This CL contains a proposed API for dealing with layout bounds.
This solution exposes:
1. Class: Insets - for storing layout Insets (and later possibly padding).
2. Methods: View:(get/set)LayoutInsets() - for storing layoutBounds.
3. Methods: ViewGroup:(get/set)LayoutMode() - for controlling layoutMode.
It also iuncudes the changes to GridLayout to support layout bounds.

- Added a new custom PNG chunk that carries the layout padding ints.
- Extract the padding ticks from .9.png images and store in the chunk.
- Load the padding information at runtime into Bitmap and NinePatchDrawable.
- The new chunk is ordered first so that it doesn't cause a problem in older
versions of the platform.

There was a lot of fancy code just above the clear to ensure
that drawables that aren't affected by the change are kept,
then the entire array was cleared. This patch removes the
clear, so that the drawables that haven't changed are really
kept, matching the logs, comments and larger part of the code.
This patch also fixes the various constant states to return
correct ChangingConfigurations.

invalidateSelf() already exists on Drawable. This triggers a call to
callback listeners so that they know the drawable has been invalidated.
For example, the background drawable on View will cause the View itself
to be invalidated.

Added null check in computeBitmapSize() to avoid unhandled
exception "java.lang.NullPointerException" at
android.graphics.Rect.<init>(Rect.java:72).
This problem was discovered in the wild.

This change only adds the necessary API and stubs. The implementation
will be added in another change.

Ummmm... this turns out to be pretty bad. NinePatchDrawable was not
scaling its reported padding for compatibility mode, causing spacing
to be off. All over the place. This change should improve things quite
a bit (and magically makes nearly all of the menu flaws go away).

Now that we are using preloaded drawables in compatibilty mode, when
constructing them from their constant state we need to set the new
drawable's target density appropriately.

Remove the stuff that doesn't use preloaded drawables when in
compatibility mode, since this works fine ever since we were able
to deal with drawables in a different density than the canvas.
Change the snapshot function on View to return a snapshot at
the same size that will actually be drawn on screen (when in
compatibility mode), to be able to show scaling artifacts and
all.
This change was original an attempt to fix issue #2101917: Text
field edges appears to be improperly rounded. That turns out to
probably be something deeper in the graphics system, but also
included here is the debugging code I did to try to track down the
problem to make it easy to turn on again later.

This change allows us to use drawables that match the current screen
density even when being loaded in compatibility mode. In this case,
the bitmap is loaded in the screen density, and the bitmap and
nine-patch drawables take care of accounting for the density difference.
This should be safe for existing applications, for the most part, since
they shouldn't really be pulling the bitmap out of the drawable. For
the small rare chance of them breaking, it worth getting the correct
graphics. Also this will only happen when there is actually a resource
of the matching density, and no existing apps should have resources for
anything besides the default density (though of course all of the
framework resources will be available in the native density).
As part of this, the bitmap density API has been changed to a single
integer provider the DPI unit density.
