The crash was caused by a dangling pointer in CPWL_ListCtrl to
the font map owned by CFF_TextObject. The order of events was:
1. ~CFFL_ListBox runs and calls parent destructor ~CFFL_TextObject.
2. ~CFFL_TextObject runs and deletes its member m_pFontMap. m_FontMap
was referenced by CPWL_ListCtrl which is now dangling.
3. ~CFFL_TextObject calls parent destructor ~CFFL_FormFiller.
4. ~CFFL_FormFiller calls DestroyWindows().
5. CFFL_FormFiller::DestroyWindows() deletes widgets, among them
CPWL_ListBox.
6. ~CPWL_ListBox deletes its member CPWL_ListCtrl.
7. ~CPWL_ListCtrl sees a dangling pointer to the map and crashes.
Making the DestroyWindows() call earlier in the destructor of
CFFL_TextObject, we execute steps 5-7 before freeing m_pFontMap.
An extra DestroyWindows() is still made in ~CFFL_FormFiller, but
it is then non-op if the derived CFFL_TextObject already called it.

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.

This class implements common code used by several CFFL_FormFiller
sub-classes. Make those sub-classes inherit from CFFL_TextField, instead
of inheriting from CFFL_FormFiller directly and then implementing the
same functionality multiple times.

This method replaces the selected text in a user-editable form text
area with another text string (which can be empty or non-empty). If
there is no selected text, FORM_ReplaceSelection() will append the
replacement text after the current caret position.

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.
