This CL is an effort to stage the conversion to named
parameters for all SkFlattenable commands. This particular
stage only does the following two things...
1. Move flattenable buffers from SkFlattenable.h into
their own header.
2. Update and Add new read write methods for better clarity
and convenience.

There are three light types for each: distant, point and spot, whose code
generation lives in a GrGLLight class hierarchy. This similar to the CPU
implementation, where each light type provides a function to compute the vector
from the surface plane to the light (surfaceToLight) and to compute the light
colour (emitLightColour). Instead of templated member functions, as in the CPU
implementation, these are virtual functions to emit the light-specific GLSL
code.
All of the code for the GPU path lives in the same file as that for the CPU
path, SkLightingImageFilter.cpp. In order to provide Ganesh a hook to access
it, SkImageFilter now has a asNewCustomStage() virtual, which allows an image
filter to return a GrCustomStage representing that filter.
Note that this patch does not handle the border conditions correctly (the
[top|bottom][Left|Right]Normal() functions in the CPU implementation). That
will come in a future patch.

light, rather than the filter, so computation is localized. Changed a couple
of non-const refs in the image filter creation API const refs. Changed "const
SkColor&" to "SkColor", since it's just a uint32_t anyway.

the caller instantiates a light (distant, point or spot), and an
SkDiffuseLightingFilter or SkSpecularLightingImageFilter with that light. A
Sobel edge detection filter is applied to the alpha of the incoming bitmap, and
the result is used as a height map for lighting calculations.

called (for now at least) TwoPointConical, to distinguish it from the
existing one (TwoPointRadial), and to reflect its odd behavior where it draws
transparent outside the boundary of the "cone" between the two circles.
This impl is unsupported by GPU and Printing at the moment, and Chrome does not
yet invoke it.

or stroke parameters for a path.
Today, the patheffect only sees if the caller was going to stroke or fill, and
if stroke, it just sees the width. With this change, the effect can see all of the
related parameters (e.g. cap/join/miter). No other change is intended at this
time.
After this change, I hope to use this additional data to allow SkDashPathEffect
to, at times, apply the stroke as part of its effect, which may be much more
efficient than first dashing, and then reading that and stroking it.
Most of these files changed just because of the new parameter to filterPath. The
key changes are in SkPathEffect.[h,cpp], SkPaint.cpp and SkScalerContext.cpp

The following changes were made by this CL:
1. Make flatten() a protected method as callers should use
SkFlattenableWriteBuffer to flatten an object
2. Make flatten a const method (including subclasses)
3. Mark subclass implementation of flatten with SK_OVERRIDE
4. Ensure overridden flatten impls call their parent
5. Remove no-op implementations of flatten from subclasses
Additionally, if necessary the unflattening constructor was
also moved to the protected section of the subclasses
header if it was not already there.

The imageblur test also needed to stop calling getDeviceSize(), since it was
returning 99999x99999 for the SkPicture case.

SkBlurImageFilter, sets it on an SkPaint, passes that paint to saveLayer(),
draws the primitives which are to be blurred, then calls restore(), which
applies the blur. The blurs have separate sizes in the horizontal and vertical
direction. This feature is GPU-only for now.
NB: Due to the clipping change, there are slight pixel differences on the
blurs_gpu and shadows_gpu tests, so those will require rebaselining on all
platforms, as will some of the WebKit layout tests (TBD).

SkGPipe needs this, since it cannot (unlike SkPicture) see all of the factories
before it hands its data to the reader.
In this mode, the writer embedds the factory name the first time it sees it,
and then after that writes an index (referencing the fFactorySet). The reader
installs an empty array, and as it encounters names, appends them to that array
so that subsequent indices can be used to retrieve the previously named factory.
Some of the existing patheffects did not register their factory names, so those
changes are also part of this CL. Annoyingly, to register your factory using the
current scheme, it has to be in the public section of the class definition.
