Wrapper code (3.4 beta 5)

Hello,

I studied the PDF wrapper code (3.4b5).
I understand the PDFView is responsible for handling the touch event and it uses the PDFVPage to draw the PDF on the screen.
I wonder what the VPage is for ? It does not seem to be related to the PDFVPage and it is used in the 3.5beta7 instead of PDFVPage to render the PDFPage.
Which on should we use ?

There are 3 modules in Demo project:
PDFReader based on PDFView classes, which using PDFVPage
RDPDFReader based on PDFLayoutView classes, which using VPage.
ViewLib which implements all base classes, it is library wrapping.

In RDPDFReader there are sample using ViewPager, based on VPage class.
