28937283e1 fix gaps in antialiased hairlines (thanks to preda)
expand SampleHairline text to check for clip violations

3c9b2a4a0e expand SkShader's flag kConstInY to 16 and 32 variants, allowing a shader
(like gradients) to support predithering. If they do, then they would suppress
kConstInY16, since they no longer are const.

The blitters now check for each flag separately, so we don't have to give up
const-in-Y in the 32bit case, since in that mode we don't care about dithering.

cafc9f9e80 fixes around isOpaque and dithering
- copyTo() now preserves isOpaqueness, and BitmapCopyTest tests it
- bitmap shader doesn't claim to have shadespan16 if dithering is on, since its
  sampler doesn't auto-dither (note that gradients do auto-dither in their
  16bit sampler)
- blitter setup just relies on the shader to report if its 16bit sampler can be
  called (allowing gradients to say yes regardless of dither, but bitmaps to say
  no if dithering is on)

07d1f008b3 add special matrixprocs when the matrix is at most translate. These are faster
(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

558434a9e1 FreeType: fix garbled bitmap glyphs.
At some point (probably in one of the LCD patches), the fMaskFormat
for bitmap glyphs changed from kA8 to kBW. Formerly, bitmap glyphs
were always transformed into A8 format. With this patch, we check the
fMaskFormat and pick the correct transform at run time.

4484d23ab4 Remove assertion in getAddrLCD.
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.

f18d876001 Add runtime detection for missing subpixel support in FreeType.
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.

ac3011c6d4 Support subpixel text when FreeType is built without such support.
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.
