bug:8409891

Snapshots frequently have their clip overwritten due to applying
deferred state - now, store tiling clip information in a separate
rect, outside of the snapshot so it isn't overwritten.

bug:8235699

Ensure rectangle clipping operations disable deferring when necessary
(i.e., when the op might create a non-rect region), including in
DisplayList::setViewProperties

Additionally, makes clipping with a kUnion always use a region, for
consistency with software rendering

Bug #7146141

This change is needed to add a render buffer cache to avoid
creating and destroying stencil buffers on every frame.

This change also allows the renderer to use a 1 bit or 4 bit
stencil buffer whenever possible.

Finally this change fixes a bug introduced by a previous CL
which causes the stencil buffer to not be updated in certain
conditions. The fix relies on a new optional parameter in
drawColorRects() that can be used to avoid performing a
quickReject on rectangles generated by the clip region.

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.

735738c4ddf3229caa5f6e634bf591953ac29944 03-Dec-2012 Romain Guy <romainguy@google.com> Preliminary Support for region clipping

Region clipping, using Canvas.clipPath or Canvas.clipRegion, requires
a stencil buffer to be always present. In addition, extra wiring is
required in JNI and display lists.

This change only adds the necessary JNI/C++ APIs and some extra
plumbing to start the real work on properly supporting region
clipping.

A new debug define called DEBUG_CLIP_REGIONS can be used to draw
the current clip region. It is off by default, as is region
clipping.

The default implementation of clipPath() and clipRegion(), now
in native, mimics the previous Dalvik implementation to prevent
regressions.

Bug #7253839

1. Make sure we don't make GL calls while recording display lists

when a perspective transformation is used on the Canvas

db8c9a6a4d9bf8c39f834b25611926caf21380f6 22-Mar-2012 Chet Haase <chet@google.com> Optimization of alpha with DisplayList properties

Some views (such as ImageView and TextView) handle non-opaque alpha
values directly. This was originally an optimization, but we can handle it faster
in many cases without this optimization when DisplayList properties are enabled.
Basically, if a view has non-overlapping rendering, we set the alpha value directly
on the renderer (the equivalent of setting it on the Paint object) and draw each
primitive with that alpha value. Doing it this way avoids re-creating DisplayLists
while getting the same speedup that onSetAlpha() used to get pre-DisplayList properties.

This adds basic support for clip regions. It is currently disabled at compile
time. Enabling clip regions will require setting up a stencil buffer.

The Snapshot class is getting complicated enough that its implementation
should now live in a separate .cpp file. This will become particularly
useful when support for clip regions and paths will be added later on.
