bug:8875715

Additionally moves op logging before the op is executed, to print
correctly, in pre-order traversal

527a3aace1dd72432c2e0472a570e030ad04bf16 04-Mar-2013 Chris Craik <ccraik@google.com> Draw Operation merging

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.

cf51a4199835e9604aa4c8b3854306f8fbabbf33 09-Apr-2013 Romain Guy <romainguy@google.com> Introduce PixelBuffer API to enable PBOs

PBOs (Pixel Buffer Objects) can be used on OpenGL ES 3.0 to perform
asynchronous texture uploads to free up the CPU. This change does not
enable the use of PBOs unless a specific property is set (Adreno drivers
have issues with PBOs at the moment, Mali drivers work just fine.)

This change also cleans up Font/FontRenderer a little bit and improves
performance of drop shadows generations by using memcpy() instead of
a manual byte-by-byte copy.

On GL ES 2.0 devices, or when PBOs are disabled, a PixelBuffer instance
behaves like a simple byte array. The extra APIs introduced for PBOs
(map/unmap and bind/unbind) are pretty much no-ops for CPU pixel
buffers and won't introduce any significant overhead.

This change also fixes a bug with text drop shadows: if the drop
shadow is larger than the max texture size, the renderer would leave
the GL context in a bad state and generate 0x501 errors. This change
simply skips drop shadows if they are too large.

bug:8480642

With the additional save/restore around the operations in flush, the
stored restore batches weren't matching up to the correct saves.

bug:8464795

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

bug:8450062

- Fixes overdraw indication with DeferredDisplayList
- Fixes drawHardwareLayer called after flush

Additionally changes drawLayer to pass its paint to native via setLayerPaint

Wrap flush in save/restore so that reordering doesn't affect final
transform

bug:8409891

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.

shape types.

This change also uses PathTessellator to render convex paths.

This avoids leaving the renderer in a state with stale pointers (to,
e.g., shaders or color filters)

Removes mMultipliedAlpha, using the snapshot alpha for all
non-overlapping display list alpha control.

Additionally, fixes opacity issues where children of
hasOverlappingRendering=false displaylists (both hw layer sublists and
other sublists with hasOverlappingRendering=false)

bug:8037003

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 deferred display lists model now allows us to precache glyphs
at their exact size on screen.

This change also removes debug markers when the renderer defers
and reorders display lists. It also adds a flush event marker.

bug:8037003

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
