8072e4fdc8 bump SkStrAppendScalar_MaxSize to 14 to accomodate the largest string now that
scalar->string uses %.8g. Floats have at most 8 significant digits, plus we add
more space for sign, decimal point and exponent.

add tests to check these limits.

Fixed rendering of shadows under bitmaps.  
Added an option to SkBlurMask to produce higher quality blurs.  
The HQ blur option is propagated through SkBlurDrawLooper so that it can be invoked by WebKit for drawing shadows.

4854327772 [PDF] Add support for xfermodes / blend modes.
- Change SkGraphicState to track and set the blend mode (xfermode) for modes built in to PDF (non porter duff modes + src over).
- Add SkXfermode::asMode() to retrieve xfermode as an enum for non porter duff modes.
- Move SkXfermode.cpp around a bit to support asMode() -- Generally move utility functions toward the top of the file.
- Make SkPDFFormXObject an isolated transparency group, as it used for saveLayer, which draws on transparent, not the device background.
- Set the graphic state in drawDevice and drawBitmap in order to get the right xfermode and alpha.

This prevents two copies of the content stream from sticking around.  It also fixes an invalid memory reference because SkCanvas::internalRestore deletes the device (maybe it should just unref) after drawing it onto the main device.

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.

2a22e10ab2 Add Truetype and Type 1 font embedding support
Sorry this is such a large CL.  It was very exploratory for me to make this
work.

- Add an interface to SkFontHost to retrieve font information and provide NULL implementations on all platforms except Linux.
- Segment large Type 1 fonts into fonts with shared resources with 255 glyphs each.
- Convert the various Type 1 formats to the form PDF wants.
- Update font as we draw text instead of as part of the graphical state.
- Remove built-in font support, we can't really use it.

Other changes I can pull out to a separate CL if you like.

- Add SkTScopedPtr class.
- Fix double free of resources.
- Fix bug in resource unique-ifying code.
- Don't print anything for any empty clip path.
- Fix copy paste error - MiterLimit.
- Fix sign extension bug in SkPDFString
- Fix FlateTest rename that was missed on a previous commit.

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.

c3856384e4 SSE2 optimizations for 32bit Color operation.
[Patch from weiwei.li@intel.com]

SSE2 optimization has been added by Stephen White before, this improves the skia
performance on SSE2-supporting platform. (please refer to below issues)

Issue 171055: More SSE2ification
Issue 157141: More SSE2ification
Issue 150060: minor tweaks to SSE2 code for -fPIC
Issue 144072: SSE2 optimizations for 32bit blending blitters

This CL implements SSE2 optimizations for the 32bit Color operation. Like above
issues, it uses CPUID to detect for SSE2 and changes the platform procs at
runtime as well. The 32bit Color operation is heavily used on Chrome HTML5
canvas operations. Take Microsoft IE test drives Pulsating Bubbles as example
(http://ie.microsoft.com/testdrive/Performance/PulsatingBubbles/Default.xhtml),
if running this cases on Chrome, the overhead of 32bit Color operation is about
40~50%. So this CL will make skia performance more better, and also make Chrome
HTML5 canvas performance more better.

Additional, this CL has passed the skia bench & tests validation, the result is
pretty good. We also apply this CL to the latest chromium, and re-run Microsoft
IE test drives Pulsating Bubbles, the performance is improved by almost 9~10%.

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

86bff1f008 Add safe size/copy functions to Skia.
This patch adds four methods to SkBitmap. There are two functions to return
    "safe size", defined as the number of pixels from the value returned by
    getPixels() to the end of the allocated buffer.

    There is one version of fillPixels() to copy the bitmap instance into an
    external buffer (with specified size, and using specified stride), and another
    fillPixels() to copy from an external buffer to the instance bitmap. In the
    latter case the specified height, width and pixel format must match that used by
    the bitmap instance, although the specified stride may be any value at least as
    large as the minimum stride for the specified geometry. It is assumed that the
    external buffer is of size at least (height - 1)*stride + width *
    bytesPerPixel.

    Both fillPixels() functions return false if the copy is not possible with the
    specified parameters.

8c1d88dcfb Remove include of SkGLDevice.h from SkGLCanvas.h
The '#include "SkGLDevice.h"' from include/core/SkDevice.h requires internal
Skia code to be added to the include search paths when using the deprecated API.
This change adds back SkGLCanvas.cpp to avoid exposing SkGLDevice.h to the
public API.

The change also includes an explicit virtual destructor on SkDeviceFactory to
silence a -Wnon-virtual-dtor warning and allow for -Werror.

4526a847da This patch allows the use of the native FreeType emboldening
algorithm when "fake bold" text is used in SkPaint.

It's enabled by #defining SK_USE_FREETYPE_EMBOLDEN.

doIRect() non-abstract so that a child class can override
either the general flavor or the text flavor.

909994fbae new scanconversion technique
This technique geometrically clips all segments against the clip bounds,
ensuring that we never send a value to the edgelist that might overflow in
fixedpoint.

Current disabled in SkScan_Path.cpp by a #define. There are a few minor pixel
differences between this and the old technique, as found by the gm tool, so
at the moment this new code is off by default.

9272761b22 SSE2 optimizations for 32bit blending blitters.
This CL implements SSE2 optimizations for 3 of the 32bit blending blitters.  It
uses CPUID to detect for SSE2 at runtime.  In order to accomodate runtime
detection, it changes the platform procs from static arrays to static
functions.

It also includes an implementation of SkTime for Win32.
