Clean up CFX_ImageTransformer parameters.

- A valid matrix is always passed in, so make the parameter const-ref.
  Since it is not obvious who owns the passed in matrix, make a copy
  with the corresponding matrix member.
- Since the matrix parameter is const-ref, CFX_DIBBase::TransformTo()
  can also have a const-ref matrix parameter.
- |flags| should be uint32_t, since |m_Flags| is.
- |pClips| is only used inside the ctor, so remove |m_pClip|.
