This code has several disadvantages over a more modern graphics engine:
- no SIMD support
- no GPU support
- limited quality
Further, calling this code locks in the perceived resolution, so that
the output cannot be scaled without additional loss.
By directing all bitmap drawing through
CFX_SkiaDeviceDriver::StartDIBits, Skia can handle all appropriate
bitmap optimizations.
To that end, SetDIBits and StretchDIBits now call StartDIBits.
Other changes:
Skia's bitmaps are premultiplied. PDF contains bitmaps that are
unpremultiplied. PDFium appears to use premultiplied bitmaps sometimes,
and unpremultiplied bitmaps elsewhere. Add a debug check for
unpremultiplied bits in Skia's driver, and add a utility to premultiply
PDFium's bitmaps' bits.
PDFium supports a 24 bit RGB bitmap padded to a 32 bit word. Set the
high byte so that Skia can treat this as an ARGB bitmap.
Defer the application of the alpha value to the draw call rather than
calling MultiplyAlpha where possible.
Allow the destination bitmap to be alpha 8 or argb 32.

This CL removes the interfaces:
* IPDF_ObjectRenderer
* IPDF_OCContext
* IPDF_RenderModule
* IPDF_PageModule
The CPDF_RenderModule was just wrapping new and delete calls. This Cl moves
those up to the callers and removes the CPDF_RenderModule class.

This CL is a straight move of the fxge includes into core/fxge/include.

Every time I read this code, I have to make the mental substituion
that "Element value" means "de-ref indirect object", so it might
as well just say so.

This CL splits apart the core/include/fpdfapi/fpdf_resource.h file and places
the classes into individual files.
