bug:14297149

SaveLayer's performance cost is high, and proportional to the surface
being projected onto. Since ripples (even unbounded ones) are now
always projected to the arbitrary background content behind them, this
cost is especially important to avoid.

This removes the last semi-secret, saveLayer from the projected
ripple implementation.

Also fixes the HW test app to correctly demonstrate this projection
masking behavior.

Additionaly, alters PathTessellator to gracefully handle
counter-clockwise paths, and simplifies the work done by
ShadowTessellator to ensure all of its paths are counterclockwise.

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: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.

28ce94a4ffc7576f40776d212f1ada79fafaa061 31-May-2013 Chris Craik <ccraik@google.com> Overdraw avoidance and merging of clipped ops

bug:8951267

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.

The renderer used to pre-cache glyphs at record time. This then changed
to pre-caching at the beginning of every frame. This unfortunately entails
a lot of duplicate work on every frame, which amounts to 0.5 to 1ms in
some stock applications.

This change is somewhere in the middle: pre-caching happens the first
time a DrawTextOp is deferred or every time the screen-space transform
is different from the last pre-caching operation.

This change extracts the scale parameters of the current transform
to pass then to the font renderer. Rotation and perspective are
applied to the generated mesh inside the vertex shader. This limits
the number of glyphs we have to create in the font cache and thus
reduces memory churn.

The drawColorRects() method was clipping individual rectangles
using the wrong parameters left, top, right and bottom instead
of l, r, t and b. It also checked for count == 0 after the loop
when it should have checked for vertexCount == 0. The quickReject
is now not part of the loop since it's a bit overkill to perform
so many matrix multiplications. What we really care about is the
final quickReject performed on the max bounds of the entire set
of rectangles.

This change also replaces all instances of mSnapshot->transform
by currentTransform() to make the code slightly more readable.

c74f45a334f0e3725c23cdd270cbcb0efac4ea75 27-Feb-2013 Romain Guy <romainguy@google.com> Properly scale text

This change does not apply to drawPosText() and drawTextOnPath() yet.

Prior to this change, glyphs were always rasterized based on the
font size specified in the paint. All transforms were then applied
on the resulting texture. This creates rather ugly results when
text is scaled and/or rotated.

With this change, the font renderer will apply the current transform
matrix to the glyph before they are rasterized. This generates much
better looking results.

8ce00301a023eecaeb8891ce906f67b513ebb42a 16-Jan-2013 Romain Guy <romainguy@google.com> Implement clipRect with a transform, clipRegion & clipPath
Bug #7146141

When non-rectangular clipping occurs in a layer the render buffer
used as the stencil buffer is not cached. If this happens on a
View's hardware layer the render buffer will live for as long
as the layer is bound to the view. When a stencil buffer is
required because of a call to Canvas.saveLayer() it will be allocated
on every frame. A future change will address this problem.

If "show GPU overdraw" is enabled, non-rectangular clips are not
supported anymore and we fall back to rectangular clips instead.
This is a limitation imposed by OpenGL ES that cannot be worked
around at this time.

This change also improves the Matrix4 implementation to easily
detect when a rect remains a rect after transform.
