This strips out last of the edge types and the fixed function edge attribute and replaces them with using GrEdgeEffect. Also fixes a minor bug when checking attribute counts -- it was using kAttribIndexCount instead of kVertexAttribCnt.

Effects can ask the builder for local coords which may or may not be distinct from positions.
GrEffectStage tracks changes to relationship between pos and local coords.
GrGLEffectMatrix and GrSingleTextureEffect can use either pos or textures as intput coords
GrSimpleTextureEffect now allows for an explicit texture coords attribute.

Adds some optimizations to the circle and ellipse shaders, static effect
instances for their GrEffects, and some minor changes to GrDrawState::setEffect
to make GrEffect setup faster.

SkPurgeableImageCache:
New image cache that uses virtual memory to store the pixels. Combines
features of SkAshmemImageCache (which has been removed) with SkPurgeableMemoryBlock, which has android and Mac versions.
SkImageCache:
Modified the API. pinCache now returns a status out parameter which
states whether the pinned memory retained the old data. This allows
allocAndPinCache to only be used for allocations.
Add a new debug only interface to purge unpinned data.
Updates to documentation, clarifying behavior.
Changed CachedStatus to MemoryStatus
SkLruImageCache:
Implement the new function purgeAllUnpinnedCaches and change implementation
of pinCache for the new behavior.
SkLazyPixelRef:
Rewrite onLockPixels to account for the new behavior of pinCache.
BitmapFactoryTest:
Test the new SkPurgeableImageCache.
Write tests which directly test the SkImageCaches.
Create a larger bitmap, since some of the SkImageCaches are designed
to handle large bitmaps.
bench_ and render_pictures:
Consolidate lazy_decode_bitmap into one function.
Allow using a flag to specify using the purgeable image cache.
Clean up some #includes.

unused headers and fixes a couple of bugs exposed by changing the random
number generator:
First, the function SkMatrix::getMaxStretch() had an error where it was testing
the square of a number against near-zero. This led to it occasionally taking a
cheaper but imprecise path for computing the eigenvalues of the matrix. It's
been replaced with a check against the square of SK_ScalarNearlyZero.
The second case was a failure in ClipStackTest, where it hit the rare case of
a practically empty clip stack (it has a single Union) and we set a tight
bounds. The bounds rect doesn't get set by GrReducedClip::ReduceClipStack() in
this case, so when it clips the reduced stack it's clipping against garbage,
and the resulting regions don't match. The solution is to initialize the
tightBounds rect.

This changes the old method of setting vertex layout to a new one where we
specify vertex attribute data separately from attribute bindings (i.e. program
functionality). Attribute data is now set up via an array of generic attribute
types and offsets, and this is mapped to the old program functionality by
setting specific attribute indices. This allows us to create more general
inputs to shaders.

I removed unused parameters in the tests wherever it was trivial to do so. I'm trying to get the easy ones out of the way before we get into more involved discussions around this.

This patch changes the semantics of tileWidth/Height to include the border region, and
uses an offset to take into account the fact that there is no outer border for outer
tiles. This patch also fixes a previous bug where the right column and bottom row were
considered to be included in bounds that are expressed as an SkIRect.

The problem fixed - http://code.google.com/p/skia/issues/detail?id=940 - is that getResources will recursively obtain all child resource recursively without checking for duplicates.
If we have lots of duplicates, then we try to build a very large vector (exponential with the number of nodes usually) and sooner or later we end up using too much memory and crash.
A possible solution could have been to make sure resources do not have duplicates, but that requirement is impractical, and it this leaves the solution fragile, if there is any issue in the tree, we crash.
When we emit the pdf, the large number of duplicates is not an issue, because SkPDFCatalog::addObject will deal with duplicates.
I have run the gm with --config pdf, and the images are 100% same bits, while the pdfs have the same size but some very small changes, the order of some objects.
