Before this change, GrStencilAndCoverTextContext would send 6-float
affine transforms to drawPaths for every glyph. This updates it to
concat the text scale onto the context matrix, and then only send
2-float translates (or 1-float x-translates when possible).
Also adds a glyph_pos_align test to gm that exercises the newly added
codepaths, and starts ignoring a few gm tests with benign pixel diffs
until we can rebaseline.

In SkPNGImageDecoder::onDecodeSubset, use png_read_rows to write to
the scratch memory provided. This is what we should have been doing
anyway. Further, writing directly to the bitmap can cause writing
to the wrong memory since the bitmap may not be as big as the
scratch memory in the case of sampling with a short bitmap.

Each patch defines a method genMesh that produces the geometry to draw. To do this they receive a SkPatchMesh object which they need to initialize in order to set up how the data is going to be formatted. Later they call function like setColor or pointAt to set the values at a specific index, the SkMeshPatch object handles the indices based on the format and makes it transparent to the client.
Added a slide to sample app to show how to set up this classes and how they interact.

For some (as yet unknown reason) the guard in ConicPathBench that disables the path_hairline_big_AA_conic case isn't working. As an alternate fix, this CL makes the Default path renderer confess its lack of support for conics and allows the Software path renderer to handle non-AA cases. This will work but the real fix is to enable conics in the Default path renderer.
Here is the situation we're seeing in the path_hairline_big_AA_conic case:
the path is a hairline drawn with AA
the render target is multisampled (so AA on the draw gets disabled)
StencilAndCover path renderer doesn't handle hairlines
AAHairLine path renderer only handles AA paths (but can handle conics)
AAConvexPath renderer also only handles AA paths
Default path renderer only handles non-AA paths (but doesn't handle conics)
Software path renderer - was disallowed from handling non-AA paths

Refactor CanvasStateTest to pull out functions which can
either be called directly or from a shared library. Add a
command line flag to pass in the path to a library to open
to call those functions from.
Separate different CanvasTest tests into separate DEF_TEST
tests. This allows them to be run in parallel.
Move the ifdefs outside of function declarations to skip
running CanvasTest tests which do nothing.
Add the canvas_state_lib target. It is a shared library that
exports some functions to be called by another version of
Skia.

Share command flags between dm and unit tests.
Also, allow dm's core to be included by itself and iOSShell.
Command line flags that are the same (or nearly the same) in DM
and in skia_tests have been moved to common_flags. Authors,
please check to see that the shared common flag is correct for
the tool.
For iOS, the 'tool_main' entry point has a wrapper to allow multiple
tools to be statically linked in the iOSShell.
Since SkCommandLineFlags::Parse can only be called once, these calls
are disabled in the IOS build.
Since the iOS app directory is dynamically assigned a name, use '@' to
select it. (This is the same convention chosen by the Mobile Harness
iOS file system utilities.)
Move the heart of dm.gyp into dm.gypi so that it can be included by
itself and iOSShell.gyp.
Add tools/flags/SkCommonFlags.* to define and declare common
command line flags.
Add support for dm to iOSShell.
