Currently, all three of CFX_Matrix::TransformRect() take in rect values
and modify them in place.
This CL converts them to take in constant values and return the
transformed values instead, and fixes all the call sites.

Re-enable individual image mask rendering to improve spool sizes, with
bug fixes and improvements:
- Fix bug with missing images by ensuring all masks are recorded
- Fix printing to landscape paper sizes
- Improve spool sizes by processing the location of the masks in the
progressive renderer when rendering to the printer instead of needlessly
fully rendering them (they will be rendered as bitmaps anyway).

This method duplicates the behaviour of the const [] operator and
doesn't offer any additional safety. Folding them into one
implementation.
SetAt is retained, since implementing the non-const [] operator to
replace SetAt has potential performance concerns. Specifically many
non-obvious cases of reading an element using [] will cause a realloc
& copy.

In the original code the method of writing of objects depends on a much unpredictable factors:
as:
1) Is there an updated version of the at least one object in the document.
2) The password is changed.
3) Was this object loaded earlier.
4) The Object is compressed and document have a password.
With these factors it is difficult to predict what will be the final file.
To reduce volatility use only one method that works in all cases mentioned.
This method is parse then serialize.

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.

Currently Find() and other methods that return a FX_STRSIZE return -1
to indicate error/failure. This means that there is a lot of magic
numbers and magic checks floating around. The standard library for
similar operations uses a npos constant. This CL implements
FX_STRNPOS, and replaces usages of magic number checking. It also does
some type cleanup along the way where it was obvious that FX_STRSIZE
should be being used.
Removing the magic numbers should make eventually changing FX_STRSIZE
to be unsigned easier in the future.

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.
