Bug #7233734
Stroked rectangles were rendered using software generated textures
which would lead to slightly misaligned results. Instead, let's use
the new convex path rendering code that will do the right thing
(and save a lot of bandwidth.)

Adding a circle of radius 0 to a path is a no-op in skia, so detect

There were two issues:
- Blending was ignored with color filters
- The addition vector of a color filter was treated as integer values
instead of float values

Bug #7158326
When scissor optimization is enabled, OpenGLRenderer will attempt to
minimize the use of scissor by selectively enabling and disabling the
GL scissor test.
When the optimization is disabled, OpenGLRenderer will keep the GL
scissor test enabled and change the scissor rect as needed.
Some GPUs (for instance the SGX 540) perform better when changing
the scissor rect often than when enabling/disabling the scissor test
often.

copies from main memory to tiles memory.

Launcher occasionally crashes with a stack trace indicating that the memory
of a Layer object is corrupt. It is possible for us to delete a Layer
structure and then, briefly, use it to draw a DisplayList again before
that DisplayList gets recreated (without the layer that got deleted).
When this happens, if the memory got corrupted, it's possible to crash.
The fix is to add Layer to the other objects which we currently refcount
(bitmaps, shaders, etc.). Then instead of deleting a Layer, we decrement the
refcount. We increment when creating it, then increment it again when it's
referenced from a DisplayList. Then we decrement the refcount instead of
deleting it, and decrement when we clear a DisplayList that refers to it.
Then when the refcount reaches 0, we delete it.

Functors in WebView were binding to different buffers than we
assumed in the toolkit, eventually causing a crash due to improper
dereferencing in the currently bound buffer. Fix is to reset state
after invoking functors.

Previously, to draw a layered view with a changed Paint object for the
drawLayer operation, you'd have to invalidate the parent view, to get the
native DisplayList to pick up the new Paint properties. This change adds
API and functionality so that the developer can call setLayerPaint(), which
does the proper invalidation (lightweight, doesn't cause redrawing the view).

boundaryWidth and boundaryLength are now distance from center, instead of
distance from edge, in order to avoid unnecessary calculation in the shader. New
calculation of these matches drawAARect.

Rendering views with alpha causes the creation of Fbo layers. These layers
are created at the size of the view, clipped by the current clip rect.
However, if the view lies completely outside the current clip rect, the
Fbo layer is created at the full size of the view and copied into place
outside of its container, causing artifacts like notification items showing
up outside the notification panel.
Fix is to note when the intersect() operation fails and to set an empty bounds
on the layer.

Chrome is disabling the scissor, which doesn't play well with our
code that assumes that we know the state of the scissor. This fix
sets up our internal state based on the actual state of the scissor
in the resume() function (which is called after any calls out to the
Chrome or Browser GL functor). This fixes intermittent rendering
artifacts, including a gray address bar (where the gray background
gets painted without the clip that is being applied to the text foreground).

Bug #6942209
The font renderer was preserving a 1 px border around each glyph to ensure
bilinear filtering would work nicely. Unfortunately, this border was not
set to 0 when glyphs were added in the cache to replace old evicted glyphs.

Alignment on paint for actual glyph drawing needs to always be left,
even when drawing centered or right aligned text. The x offset for
alignment is applied by OpenGLRenderer::drawText (and needs to be early
in the pipeline for quickReject to work). Similar change needed for
drawing drop shadow.
Also fixes bug with mispositioned underline (offset for alignment has
already been applied once, no need to do it again in
drawTextDecorations).
Change-Id: Id3dcd62de5536a26b158d768889273a1492b35d6
This implementation adds a drawGeneralText() method to the OpenGL
Renderer, which supports both a global x, y position, an array of
individual glyph positions, and also a length parameter (which enables
drawing of underline and strikethrough. It also adds the method to the
display list (with marshalling and unmarshalling).
With this change, the existing drawText() method is removed entirely, as
it's subsumed by the new method. It's easy enough to revert to the old
functionality if needed by passing in a NULL positions array.

This patch adds support for drop shadows (setShadowLayer) for
drawPosText in the hwui renderer. In and of itself, it's not very
important, but it's on the critical path for correct mark positioning,
tracked as bug 5443796.
The change itself is fairly straightforward - it basically just adds an
extra "positions" argument to all draw and measure methods on the code
path for drawing drop shadowed text, as well as to the cache key for
cached shadow textures.
