- Shaders, or as they are referred to in PDF, patterns, are drawn in the coordinate system of the initial page, so when we canonicalize them, we have to consider the current transform and where they are constructed.
- Image shaders are tiled by default, this makes repeat and mirror modes easy, but means we have to draw a pattern as large as the current clip to support clamp mode.
- Gradient shaders are implemented with type 4 functions, which are basically small snippets of post script code. I've tried to make the code generation modular and heavily commented to make it easy to understand or expand.

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.

Supports fakeBold, underline, strikethrough, mode (fill, stroke, both), size, skew, alignment (left, center, right).
Missing is drawFontOnPath and font lookup and embedding.
Changed SkPDFString to support how it is used from drawText methods.
Moved compile assert into SkTypes.
Moved constants and utility function used to support fakeBold, underline, and strikethrough into higher level locations.

Reorganize how the PDF graphic state stack is managed (fixing several bugs incidentally).
Style: fix variables with underscores.
Bug: fix image matrix application order, which enabled a small refactor.

Fix the spelling of resource in several places
Make getResouce(resourceList) part of SkPDFObject
make SkDynamicMemoryWStream::getOffset and SkPDFPage::getMediaBox const
Add a temporary NOT_IMPLEMENTED macro instead of using SkASSERT

These are not the capabilities of the factory, but of the device. Additionally, it is more often needed when you have a device then when you have a factory, which caused creating of a new factory.
