1d8e194661085f9a18ab1b3cd12f9e19d3a86be5 03-Mar-2016 Doris Liu <tianliu@google.com> Make AVD thread safe

This CL introduces staging properties to VectorDrawable, which holds
properties coming from UI thread. When staging properties are changed,
they are marked dirty, and the staging properties then get pushed to
RenderThread at sync point. In cases where no staging property has
been changed, at sync point we sync the render thread properties back
to staging properties to reflect the latest render thread animation
value change.

Also, update Vector Drawable bitmap only when it's dirty

e75ab4c26a4f661334845f7bc4132011694836a4 07-May-2015 John Reck <jreck@google.com> Remove SkBitmap from ResourceCache

Bug: 18928352

Fully-proper refcounting via SkBitmap/SkPixelRef, no more
side-channel refcounting via ResourceCache. Makes HWUI
more resilient to the bitmap being modified as well as
the SkBitmap's info & rowBytes() is updated every time
a DisplayList is recorded instead of relying on buggy
cache eviction logic

ee248599d49a15fc207c5aeb0b90ec263cc1d600 12-Feb-2015 Derek Sollenberger <djsollen@google.com> Refactor DisplayList path caching.

This removes dependence on SkPath ptrs that HWUI does not control
the lifecycle of. This clears up some errors where the paths are
not generated from Java, but rather the Skia test suites.

Cherry-pick of a change that originally landed in master-skia and is
dependent on a skia merge (ag/655422).

This enables us to...

1) simplify the lifecycle/ownership between Java and HWUI
2) remove DisplayListRenderer::drawBitmapData and associated logic
3) track pixel lifecycle using standard SkPixelRef refcounting
4) Remove uncessary calls to ref/unref the bitmap's pixels and colorTable

Bug: 17947547

Pull the ResourceCache (aka, ref-counting side channel) out of
Caches so that DisplayListRenderer doesn't use Caches, avoiding
the risk of instantiating Caches on the wrong thread or

Instead of duplicating internal info about SkShader, inspect the
SkShader installed on the SkPaint.

Remove setupModifiers, nResetModifiers, and nSetupShader.

Remove calls to create/destroy the (previously) attached SkiaShader.

Remove native code for setupShader and resetModifiers.

Remove code keeping track of native SkiaShader.

Include Extensions.h.

Compare shaders on the paint, instead of on DrawModifiers.

Remove vector of SkiaShaders.

Access the SkShader on mPaint.
Remove SetupShaderOp and ResetShaderOp.

Remove resetShader, setupShader, refShader, and mShaderMap.

Pass SkShader to setupDrawShader and setupDrawShaderUniforms.

Add LayerShader, a class inheriting from SkShader, to mimic the
behavior of SkiaLayerShader. Unlike SkiaLayerShader, it can be set on
the SkPaint so it can be inspected later.
Set a LayerShader instead of a SkiaLayerShader.
setupDrawShader and setupDrawShaderUniforms now inspect an SkShader
passed in.
Inspect SkShader instead of mDrawModifiers.mShader.
Remove resetShader and setupShader.
setupDrawColorUniforms now takes a boolean indicating whether there is
a shader.
Add an inline function for accessing the SkShader on an SkPaint.
In setupDrawBlending(Layer*, bool), do not check the shader (which will
never be set), but do check whether the color filter may change the
alpha (newly fixed behavior).
In setupDrawBlending(SkPaint, ...), check the SkShader and whether the
color filter affects alpha (the latter is new behavior).

Remove pure virtual functions setupShader and resetShader.

Remove functions for refing/unrefing shaders.

Much of this code was redundant and has been removed.
Convert structs into class with nothing but static functions for
calling describe/setupProgram.

Use the SkPixelRef as the key to the bitmap Lru cache, since shader
inspection will provide a different SkBitmap pointer (though it will
hold the correct SkPixelRef with the correct generation ID).

Update manual test to have more shaders: radial, sweep, compose,
invalid compose.

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

quickReject and quickRejectNoScissor have been renamed and refactored:
- to make the scissor side effect clear and explicit
- dangerous methods no longer public
- to make the simple quick reject check logic const
- simple quick reject is now conservative

This CL also fixes several issues with line and point quickRejection -
sub-pixel and hairline lines are much less likely to be incorrectly
rejected, especially at small canvas scale.

Additionally, alpha modulation for AA points < 1px in size is now
correct, dumplicating SW behavior (similar to lines and stroked
shapes work).

This change adds refcounting of Res_png_9patch instances, the native
data structure used to represent 9-patches. The Dalvik NinePatch class
now holds a native pointer instead of a Dalvik byte[]. This pointer
is used whenever we need to draw the 9-patch (software or hardware.)

Since we are now tracking garbage collection of NinePatch objects
libhwui's PatchCache must keep a list of free blocks in the VBO
used to store the meshes.

This change also removes unnecessary instances tracking from
GLES20DisplayList. Bitmaps and 9-patches are refcounted at the
native level and do not need to be tracked by the Dalvik layer.

259b696b00f07938569fc9a0ea43858cdaab909b 04-May-2013 Chet Haase <chet@google.com> Fix scaled-view droppings artifact

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.

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.

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.

A recursive drawDisplayList call is now entirely deferred before

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.
