This will allow us to inspect the paint for thing other than
color and xfermode, such as SkColorFilters and SkShaders.

Fixes the simplifying assumption that shadow casters were always
rectangular.
Java side APIs + plumbing to pass down correct shapes still need to be added.

Adds temporary logging which should log/crash earlier on incorrectly
reordering hierarchies.

The eventual goal is for the StatefulBaseRenderer to serve as the
common base class between the DisplayListRenderer and OpenGLRenderer.
This will separate DisplayList recording, Snapshot stack management,
and the GL in OpenGLRenderer.
Additionally, avoid sp<> parameters, and use const parameters in
several places, with the intent of greatly reducing the surface area
where renderer subclasses can modify snapshot stack.
Next steps:
-move bulk of clipping logic into StatefulBaseRenderer
-disable direct snapshot access

This will eventually serve as a base class to allow
DisplayListRenderer to split off from OpenGLRenderer, and could
eventually support other rendering approaches, such as an
SkCanvas/SkPicture.
This will also be the main source of (implementation-independent)
documentation of the canvas/renderer methods.

Basically we compute the shadow as a strip of triangles, whose alpha value
is the strength of the shadow.
We use the normal to extend the geometry.
And we use static function and try to avoid new/malloc in the computation.

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

bug:4351353
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).

Fixes: This patch makes sure that the layer's alpha value is
up-to-date and does not reflect the previous view's alpha value.
it fixes the square block on marquee fading edge when text view
is applied transparency.

bug:10863163
This fixes two issues
The check for pure translation was incorrect. It was fixed and renamed
for clarity.
Certain matrix paths weren't setting kTypePositiveScale. For
simplicity (and because positive scale is simple to check) removed
flag in favor of dynamic checking.

bug:10761696
Avoids a case where a rect with top coordinate of (e.g.) 0.51f is
assumed to not draw in the first row of pixels, which leads to it not
being clipped. Since rounding can cause it to render in this first
pixel anyway, we very slightly expand geometry bounds.
Now, in ambiguous cases, the geometry bounds are expanded so clipping
is more likely to happen.

Bug: 10677765
enableScissor() must precede setScissorFromClip() as
otherwise setScissorFromClip() doesn't do anything.
Also make sure to call setScissorFromClip() if
enableScissor() returns true as enableScissor() calls
resetScissor() if the scissor state has changed.

(cherry picked from commit 5c7d5ab878b26f855175a3305a14ac12fcacf25e)
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.

Quite a few things going on in this commit:
- Enable bitmap strikes by default in Paint objects.
The SkPaint parameter that enables bitmap strikes was not previously
included in DEFAULT_PAINT_FLAGS. This effectively disabled bitmap
fonts. Oops! It's for the best, though, as additional work was needed
in Skia to make bitmap fonts work anyway.
- Complain if TEXTURE_BORDER_SIZE is not 1.
Our glyph cache code does not currently handle any value other than 1
here, including zero. I've added a little C preprocessor check to
prevent future engineers (including especially future-me) from
thinking that they can change this value without updating the related
code.
- Add GL_RGBA support to hwui's FontRenderer and friends
This also happened to involve some refactoring for convenience and
cleanliness.

An array of indices local to a layer would only be necessary if
we changed the way we resolve T-junctions. Since we only ever
draw quads, let's just use the indices we use everywhere else.
This change also uses the global indices array to render list
of colored rectangles to save on the number of vertices generated
CPU-side.
