The cbox values are long. We should make sure they are not too big before putting them into FX_RECT, which holds integers. The bound is chosen to also avoid overflow when multiplying by 1000.

This Cl removes the rect based transform method which internally just called the matrix tranform method. The callers have been reversed to make it clearer the matrix is transforming the rect.

2016-10-10Move ToString() and friends from CPDF_Object.h to CPDF_String.htsepez
Ditto with the other ToXXX functions to CPDF_xxx.h. Shortly, we will want to introduce another variant: inline std::unique_ptr<CPDF_String> ToString( std::unique_ptr<CPDF_Object>); This will require that CPDF_String be complete which is not the case in the CPDF_Object.h header. Rather than dragging all the other .h's into it, move these to the subclass headers. That way, these will be together when the new form is added.
