- The agg driver never initializes an ICC transform and always uses an
alpha_flag equal to 0 in a couple of methods.
- The skia driver is not using CFX_Renderer. If it needs it later, we should
move it out of fx_agg_driver.cpp into its own file, instead of duplicating the
code.

Rename CFGAS_TextStream to CFGAS_Stream. CFGAS_Stream is converted
to a base class instead of accepting an IFGAS_StreamImp. Things
which inherted from IFGAS_StreamImp now inherit from CFGAS_Stream.
The stream type inputs are changed to IFX_SeekableStream so that
they can accept the same type (IFX_SeekableStream is an
IFX_SeekableWriteStream and an IFX_SeekableReadStream). This way
the storage can be shared in the base class.

Re-write to use std::vectors rather than self-managed buffers.
Includes test case that breaks before patch.
Formerly, we had two independent buffers whose position were
tracked by the same variable, assuming that only one was
being written to at a given time. This is a bad idea because
it's easy to forget to zero the index when switching buffers,
and start indexing into one using previously computed offsets
from the other.
Additionally, there were cases where the location of a partial
entity wasn't discarded when switching states thus clearing the
buffer tracking said entity.

This CL applies several fixes to the fallback font code.
- PDFium uses -1 to indicate that no glyph index was found, but freetype uses
0. In CPDF_TrueTypeFont, an index of 0 indicates a freetype failure, which
means we should try to find the glyph from a fallback font.
- Improve the fallback glyph calculation by going from original font charcode
to unicode to fallback font charcode.
- Consider the m_ExtGID on Mac when deciding the fallback.
