Fixed rendering of shadows under bitmaps.

The HQ blur option is propagated through SkBlurDrawLooper so that it can be invoked by WebKit for drawing shadows.

82065d667f remove SkRefCnt safeRef() and safeUnref(), and replace the call-sites with
SkSafeRef() and SkSafeUnref().

This is basically a bug waiting to happen. An optimizing compiler can remove
checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on
precisely this check...

void SkRefCnt::safeRef() {
    if (this) {
        this->ref();
    }
}

Since a compiler might skip the if-clause, it breaks the intention of this
method, hence its removal.

static inline void SkSafeRef(SkRefCnt* obj) {
    if (obj) {
        obj->ref();
    }
}

This form is not ignored by an optimizing compile, so we use it instead.

29e5054dd0 Fix perf regression in Color32.
The regression was due to the fact that we were calling PlatformColorProc() for
every span (which in turns makes CPUID, a fairly expensive call).  Since we draw
a lot of rects, and rects have 1-pixel wide spans for the vertical segments,
that's a lot of CPUID.

Fixed by cacheing the result of PlatformColorProc(), as is done for the other
platform-specific blitters.

038aff623d Patch by Mike Lawther (mikelawther@chromium.org).
The HTML5 canvas client of BlurDrawLooper needs the option to not apply the
canvas transform to the blur offset.

see
http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-elemen...
- "The shadowOffsetX and shadowOffsetY attributes specify the distance that the
shadow will be offset in the positive horizontal and positive vertical distance
respectively. Their values are in coordinate space units. They are not affected
by the current transformation matrix."

This patch is part of fixing

512a87641f make the 16bit cache larger, to handle multiple colors in the gradient w/o
obvious artifacts. We need a more comprehensive fix for all gradients (32bit
and 16bit) when we have a large number of colors (or they are spaced out very
non-linearly), to avoid banding.

c4cae85752 add BlitRow procs for 32->32, to allow for neon and other optimizations.
call these new procs in (nearly) all the places we had inlined loops before.
In once instance (blitter_argb32::blitAntiH) we get different results by a
  tiny bit. The new code is more accurate, and exactly inline with all of the
  other like-minded blits, so I think the change is good going forward.

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.
