Previously, display lists were used only if hardware acceleration
was enabled for an application (hardwareAccelerated=true) *and* if
setDrawingCacheEnabled(true) was called. This change makes the framework
use display lists for all views in an application if hardware acceleration
is enabled.
In addition, display list renderering has been optimized so that
any view's recreation of its own display list (which is necessary whenever
the visuals of that view change) will not cause any other display list
in its parent hierarchy to change. Instead, when there are any visual
changes in the hierarchy, only those views which need to have new
display list content will recreate their display lists.
This optimization works by caching display list references in each
parent display list (so the container of some child will refer to its
child's display list by a reference to the child's display list). Then when
a view needs to recreate its display list, it will do so inside the same
display list object. This will cause the content to get refreshed, but not
the reference to that content. Then when the view hierarchy is redrawn,
it will automatically pick up the new content from the old reference.
This optimization will not necessarily improve performance when applications
need to update the entire view hierarchy or redraw the entire screen, but it does
show significant improvements when redrawing only a portion of the screen,
especially when the regions that are not refreshed are complex and time-
consuming to redraw.

When someone referenced an empty string by putting in the special value
"@null" the string block was kept, but when filtering themes this wasn't
filtered because the framework thought it was actually a null string.

This enables the system bar to carve out a region through which
events will be sent to the IME behind it.

Also hide the bitmap thumbnail stuff, we can't support it in its
current form.
And fix some bugs with propagating paths to native code. Yikes!

This change implements the onFrameAvailable callback for the
SurfaceTexture java class. It includes the C++ SurfaceTexture code as
well as the JNI and Java code to enable the callback.

The new implementation relies on OpenGLRenderer's existing layer
code instead of duplicating it. The new code is much cleaner, with
simpler and better APIs and allows tracking of drawn regions inside
layers. Region tracking is not yet enabled but this will be done
in a future CL.

With this new backend, a hardware layer is only recreated when
its associated view is udpated. This offers fast composition
in GL and fast update of the layer in GL as well.

The code was checking errno instead of the return value from the call.
This fixes calls to setreuid(), setregid(), and setpgid().

Bug #3299324
This is needed for ADT, which does not rely on Skia's reference counting
to correctly keep track of the native objects.

the reason for bug:3281533, bug:3127159 is probably too many cursors are left
un-closed in the process.
print the info on the number of cursors left open when the exception
"cursorwindow allocation failed" occurs.
This should help us figure out if that indeed is the reason
and which process is leaving the cursors open.

let cursor window size be set per device in device resources file.
default is 1MB.
for SR, it is 2MB.
it can be set to any value (in kB) in the device resource

To make a 800 tall screen run like a 720:
adb shell setprop persist.demo.screensizehack 800=720
Note this is a persistent property, so it will (intentionally) remain across boots.

The second argument of the JavaPixelAllocator constructor was
eliminated by an earlier change but the class definition was not
updated to match that edit.
