add beforeChild/afterChild methods for parents to wack the canvas before/after
it draws. These are called after the std child-view translate and clip, unlike
beforeChildren/afterChildren

(somewhat) than their scale counterparts, but are also numerically exact for
any size bitmaps. The scale versions, because they operate in a scaled 65535
space, are not always exact for large images (due to SK_Fixed1 / width) loss of
bits

Because the underlying mask extends a pixel to the left and right (or
top and bottom on vertical LCDs), the requested pixel can actaully be
one pixel outside the bounds, thus this assertion is incorrect.

- remove neon-specific functions that were not faster than the C version
- move the neon filter function to its own header, so it could be use in more places

r291 added support for building on platforms where subpixel support
has been compiled out of FreeType. However, it turns out that there is
a common situation in which we build on platforms with subpixel
support, but have to run without it: people downloading Chromium from
the buildbots.
Because we this, we need a runtime solution. Modifying the conversion
routines for this seems suboptimal because the extra branches will
slow down everyone. So we probe subpixel support at runtime by trying
to install a low-pass filter. If we fail at this, then we map all the
SkScalerContext::Rec structures to remove subpixel mode.

This reverts commit r291. It will be replaced with another solution in the next
commit.

On Fedora, at least, FreeType is built without subpixel support. It
tries to simulate subpixel mode by replicating the gray-values three
times. However, it fails to simulate the actions of the low-pass
filter and so doesn't add border around the glyphs. This patch adds a
compile-time constant, which is the number of bytes of filter border.
If this value is zero (because FreeType is simulating subpixel
support), then we add a transparent border ourselves when transforming
from FreeType rendered glyphs to masks.

Now that Chrome is rendering subpixel text, I was able to try running
the renderer process under valgrind, which turned up a number of
issues.
First, I was calculating the stride of vertical LCD glyphs wrong
(typo).
Secondly, I was going horribly wrong when a glyph was being blitted at
the edge of a bitmap. I suspected something was wrong with the code,
but I wasn't clear enough with the structure of the code when writing
it to figure out what the correct solution was.
