Previously, when a DisplayList operation was rejected because it was not
in the clip bounds, the code would not properly restore the previous
state, leading to errors in alpha values of the noop'd op being applied
to unrelated operations later in the DisplayList.

Previously text bounds were calculated to be from 0 to totalAdvance in
the X, and from the font's top to bottom. These are incorrect,
especially in light of the font fallback mechanism.
Now, we calculate the bounds of the text as we layout each glyph.
Since these are much tighter bounds in the common case, this
significantly reduces the amount of clipping required (which in turn
enables more aggressive text merging).

If Atlas::terminate() is called twice without an init() in between
libhwui would double-free Atlas::mImage. This lead to a lot of crashes
with the monkeys as they can easily trigger memory trims.

The counter can be enabled by setting the system property called
debug.hwui.overdraw to the string "count". If the string is set
to "show", overdraw will be highlighted on screen instead of
printing out a simple counter.

Sometimes views that are scaled leave behind rows/columns on the
screen as they move/scale around.
The problem was that the pivot point around which the scale takes place
(in the default case of scaling around the center of the view)
was getting truncated to integer coordinates in the display list.
Meanwhile, the pivot point at the Java level was using the true float
values, resulting in a mis-match between the invalidation rectangle
(computed at the Java level) and the drawing-operation rectangle (computed
at the native level).
This only occurred when views had odd bounds (thus the integer representation
of the center differed from the float representation of the center), and only
when some other drawing operation would expand the clip rect to allow the
incorrect drawing operation (using the wrong pivot point) to draw outside of
its clip boundaries.

When the Android runtime starts, the system preloads a series of assets
in the Zygote process. These assets are shared across all processes.
Unfortunately, each one of these assets is later uploaded in its own
OpenGL texture, once per process. This wastes memory and generates
unnecessary OpenGL state changes.
This CL introduces an asset server that provides an atlas to all processes.
Note: bitmaps used by skia shaders are *not* sampled from the atlas.
It's an uncommon use case and would require extra texture transforms
in the GL shaders.
WHAT IS THE ASSETS ATLAS
The "assets atlas" is a single, shareable graphic buffer that contains
all the system's preloaded bitmap drawables (this includes 9-patches.)
The atlas is made of two distinct objects: the graphic buffer that
contains the actual pixels and the map which indicates where each
preloaded bitmap can be found in the atlas (essentially a pair of
x and y coordinates.)
HOW IS THE ASSETS ATLAS GENERATED
Because we need to support a wide variety of devices and because it
is easy to change the list of preloaded drawables, the atlas is
generated at runtime, during the startup phase of the system process.
There are several steps that lead to the atlas generation:
1. If the device is booting for the first time, or if the device was
updated, we need to find the best atlas configuration. To do so,
the atlas service tries a number of width, height and algorithm
variations that allows us to pack as many assets as possible while
using as little memory as possible. Once a best configuration is found,
it gets written to disk in /data/system/framework_atlas
2. Given a best configuration (algorithm variant, dimensions and
number of bitmaps that can be packed in the atlas), the atlas service
packs all the preloaded bitmaps into a single graphic buffer object.
3. The packing is done using Skia in a temporary native bitmap. The
Skia bitmap is then copied into the graphic buffer using OpenGL ES
to benefit from texture swizzling.
HOW PROCESSES USE THE ATLAS
Whenever a process' hardware renderer initializes its EGL context,
it queries the atlas service for the graphic buffer and the map.
It is important to remember that both the context and the map will
be valid for the lifetime of the hardware renderer (if the system
process goes down, all apps get killed as well.)
Every time the hardware renderer needs to render a bitmap, it first
checks whether the bitmap can be found in the assets atlas. When
the bitmap is part of the atlas, texture coordinates are remapped
appropriately before rendering.

Changes:
- The static device version of libandroidfw now includes
the extra functions needed by aapt. I could only find
a few host tools that use the static library, so this is
hopefully not a problem.
- The pseudolocalization code is moved into aapt.
It was previously in libhost, but only used by aapt.

The rendering code optimizes by rejecting drawing operations that
lie outside of the bounds of their views. This works in most
situations, but breaks down when containers have called
setClipChildren(false), because we reject drawing that is outside
of that container, but which should be drawn anyway.
Fix is to pass in the value of that flag to the DisplayList drawing
routines which take that flag into account when deciding whether
to quickReject any particular operation.

Previously we prevented ops with non-translate transforms from
merging, but missed the case of the first op in a merging batch
containing a non-translate transform.
This fulfills the assumption of drawText's non-immediate mode that
merged ops will have pure translate transforms.

A clipped saveLayer will cause two draws - first to an onscreen
buffer, then again back to the framebuffer. This change - when in
overdraw debug - reissues draws associated with a clipped saveLayer,
but only to the stencil buffer. Operations within a saveLayer are
shown correctly to be twice drawn, and View.setAlpha() without an
associated hardware layer, or hasOverlappingRendering() are made more
visible.
Hardware layers, on any frame that they are updated, similarly draw
twice, and will also be counted against the stencil buffer doubly.
Note: greater depths of layers - e.g. a saveLayer within a saveLayer -
are not respected, as that would require additional region tracking.

Merge simple bitmap draw operations and text operations to avoid
issuing individual gl draws for each operation. Merging other ops to
be done eventually.
The methods are different - the bitmap merging generates a single
mesh for reused, unclipped images (esp. repeated images in a listview)
The text approach queries just defers the normal font rendering until
the last drawText in the sequence that can share the same shader.
Patches are sorted and merged, but don't yet have a multiDraw
implementation. For now, the pretending-to-merge gives better sorting
behavior by keeping similar patches together.
