bd2724f672 Fix valgrind warnings triggered in vertical mode. 
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.

36a4c2aa2d Add SkFontHost::FilterRect() which allows the font host to filter our request 
before we turn it into a font-cache entry, for the cases where the scaler will
ignore and/or collapse certain feature requests (e.g. doesn't support all levels
of hinting)

309485b7b5 Subpixel glyph rendering support. 
This patch adds support for rendering subpixel glyphs (using
Freetype). In order to control this rendering see
SkPaint::setLCDRenderText in SkPaint.h.

To setup the LCD mode, see SkFontHost::SetSubpixelOrientation and
SkFontHost::SetSubpixelOrder in SkFontHost.h.

This patch also adds more fine grained control over hinting (again,
only for Freetype currently). One can now control the hinting with
SkPaint::setHinting.

32a4249cbd make a deep copy in CreateCGImageRef if we're 565, but first upscale to 32bit. 
this at least draws the right colors, since we're 565 and CG only supports 1555
(unless someone knows how to tell CG we're 565...)

Enable dither in sample gradients, so the 4444 case isn't so ugly
