* Add a config flag to ignore the restrictions
* Apply restriction to both SkPDFScalar and scalars used in content streams.
* +/- 32,767 for the integer part.
* +/1 1/65536 for the fraction part.

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.

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.

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.

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.

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)
