The existing behaviour was to clamp the provided index to the valid
bounds. This would lead to programming errors being hidden, since
inserting would still do something even if the index calculation was
wrong. The behaviour of these methods has been changed to instead
early return when this occurs, returning the old length value. The
caller can check if the call to Insert actually did anything by
comparing the returned value to the length before calling insert.
All of the existing calls to Insert have been tested by running all of
the tests with asserts in the Insert method to check the index is in
bounds. Additionally the call sites have been manually inspected. The
majority of them are of the form Insert(0, foo) and the rest tend to
be in a loop advancing from 0 to length.
Convenience methods InsertAtFront/InsertAtBack have been added to
handle calling Insert when the intent is for the character to be added
to the beginning or end of the string. Existing call sites to Insert
that do this have been converted.
This work was originally being performed to check if there would be
any issues in these methods with making FX_STRSIZE unsigned.

The various string/byte classes support Mid(), Left(), and Right() for
extracting substrings. Mid() can handle all possible cases, but Left()
and Right() are useful for common cases and more explicit about what
is going on.
Calls like Mid(offset, length - offset) can be converted to
Right(length - offset). Calls like Mid(0, length) can be converted to
Left(length).
If the substring being extracted does not extend all the way to one of
the edges of the string, then Mid() still needs to be used.

This support is being removed from CFX_ByteString, CFX_ByteStringC,
CFX_WideString, and CFX_WideStringC. This standardizes all of these
classes to only have one Mid method that takes in 2 params, offset and
count. Count now must be positive. The old behaviour of calculating
the length for the user if -1 is passed in for the count has been
removed. This work is in preperation for converting these classes to
not accept negative lengths anywhere and thus make the underlying size
type unsigned.

This CL uses the following algorithm for improving substitute font spacing (we
are assuming the text layout is horizontal):
* Calculate PDFWidth, the width that the PDF says the glyph should have.
* Calculate FTWidth, the width calculated by freetype for the glyph, using the
substitute font that we'll use to render it. Note that some embedded fonts have
PDFWidth == FTWidth + 1, so we consider that to be matching widths.
* If PDFWidth > FTWidth + 1 , move the x coordinate by the difference / 2 so
that the glyph is rendered in a more centered spot and the text looks better.
* If PDFWidth < FTWidth, transform the glyph horizontally by PDFWidth / FTWidth
so that the glyph gets compressed and does not overlap with surrounding glyphs.

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.
