The order of the elements in the header is correct, but we
were clearing it early in the destructor itself.

The owned copy needs to be modified, so it should be non-const. Whereas
the unowned copy can be const.
Add a GetClonedDict() method for accessing the modifiable dictionary.

This existing code has the potential for an integer overflow in it.
When overflow occurs in this function scaling may partially succeed.
This is due to how out of range values are being clamped, which
implicitly swallows the overflow.
This CL changes the calculation to be performed in a 64-bit space and
then attempts to down cast it back to 32-bit space at the end. Because
there are multiple steps it is possible for an intermediate value to
cause an overflow in 32 bit space, but the final value to be valid. If
the downcast is not possible then the stretch operation is failed.
An existing test case has been updated, since it encoded an incorrect
result.

This is an obstacle to introducing dummy CPDF_Pages to underly all
CPDFXFA_Pages, since we would then have a parserless CPDF_Page, whose
parse could never succeed or fail. The m_ParseState would never change,
and if the caller dutifully recalls us until that changes, we hang.
Small separate CL since it might impact non-XFA cases unexpectedly.

Should FPDFDocumentFromCPDFDocument() be called several times under
XFA, we may WrapUnique() the document several times. So cache a pointer
back from CPDF_Document to CPDFXFA_Context to avoid this.
Because of layering, introduce a placeholder type CPDF_Document::Extension.
This is actually the first step in some larger XFA ownership cleanup, but
makes a nice standalone CL around the one particular issue.

Currently, one gets data from CPDF_PatternCS via its parent class's
GetRGB(const float* pBuf) method. To squeeze through this interface, the
caller has to pass in a float*, and CPDF_PatternCS::GetRGB() has to cast
it to PatternValue*.
Instead of doing casting, add a specialized GetPatternRGB() method to
CPDF_PatternCS. In its parent class, CPDF_ColorSpace, add AsPatternCS()
so callers can get a CPDF_PatternCS* from a CPDF_ColorSpace*. Change
existing callers to use these new methods.
