True 3d transformations are now supported by DisplayLists and the
renderer, initially with the translationZ property on view.
Renderer operations used directly by DisplayList (formerly,
clip/save/restore/saveLayer) are now more simply managed by allocating
them temporarily on the handler's allocator, which exists for a single
frame. This is much simpler than continuing to expand the pool of
pre-allocated DisplayListOps now that more operations are called
directly by DisplayList, especially with z ordered drawing.
Still TODO:
-APIs for camera positioning, shadows
-Make Z apis public, and expose through XML
-Make invalidation / input 3d aware

Instead of storing DeferredDisplayState within an op (thus forcing ops
to be tied to a single state instance), associate each op with a new
state at DeferredDisplayList insertion time.
Now, DisplayLists (and the ops within) can be reused in a single
DeferredDisplayList draw call, as ops will use different state
instances at different points in the frame.

Bug #10185769
The assets atlas contains assets that need to be blended and assets
that do not need to be blended. With a single merge id, currently
set to be the pointer to the atlas itself, draw ops merging could
generate batches of commands containing both opaque and translucent
assets. The blend state was chosen from only one of the assets in
the batch, leading either to inefficiencies (blending large opaque
assets) or incorrect behaviors (not blending translucent assets.)
This change introduces two new merge ids in the atlas: an opaque
key and a blend key. These keys are simple booleans set to false
and true respectively (the values do not matter really.) Their
memory addresses are used as the merge ids when createing draw ops
batches, allowing all opaque ops to be batched together and all
translucent ops to be batched together.

By having quickReject round out the window-space geometry bounds, we
prevent the AA perimeter (which falls outside the local bounds passed
in) from drawing outside the clip.

If an opaque op, or group of opaque ops covers the invalidate region,
skip draw operations that precede it.
Clipped operations may now be merged, but only if they share a
clipRect - this is a very case for e.g. ListView, where all background
elements may now be a part of the same MergingDrawBatch.
It is this more aggressive merging that groups together clipped
background elements in the ListView case, enabling the overdraw
avoidance skipping the window background.

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.

bug:8540150
Layers now require traversal in update order, as it will be child
first, then parent for layer-in-layer
Fixes issue with deferred layer playback not flushing in order, and
thus child not painting before parent
Also fixes DisplayList to only be cleared after flush in deferred list

Changes drawModifiers and alpha to be restored for all operations,
since saveLayer/restore use these values, not just draw operations
Also forces a renderer state restoration before a deferred restore op
is played back, in case it is associated with a saveLayer that
doesn't have the save_clip flag set

This change defers drawing into layers until after the renderer for FBO0
is ready to draw. At that point, all the precaching is done which means
all glyphs can be uploaded at once in the font caches.

In order to defer fbo-targetting saveLayer operations, it's necessary
to update the snapshot at defer time so that deferred display state
(namely, clip and transform) are fbo relative.
Re-enables deferring, as the issues with saveLayer are fixed.

A recursive drawDisplayList call is now entirely deferred before
playing back to the screen and issuing GL commands. This way, the
entire stream can be inspected, optimized, and batch work (such as
uploading textures) before issuing commands.
Additionally, this fixes an issue where operations draw could move
across restores corresponding to saveLayer(alpha). Those and other
similar cases (such as complex clipping, requiring the stencil) are
now treated as batching barriers, with the operations that change
renderer state in a way that's difficult to defer are just re-issued
at flush time.

The reordering enables similar operations to draw together, minimizing the
OpenGL state change operations that go inbetween draws. Eventually, multiple
complete canvas draw operations will be merged (into a single glDrawArrays call,
for example)
Reorders DisplayList draw operations when:
-They can move backwards in the command stream to be after similar
operations without violating draw ordering
-The OpenGLRenderer is in a simple, replayable state (no complex clip,
or filter/shadow etc)
Also adds two system properties to control the deferral/reordering:
"debug.hwui.disable_draw_defer"
"debug.hwui.disable_draw_reorder"
which can be set to "true" to control the display list manipulation
