Hi Prawn team:

1. I found pdf header always be covered by contents.

but when i changed document.rb -> row 235:

 @y = @bounding_box.absolute_top change to @y = @bounding_box.absolute_top - 40

then this problem gone.

1. There are 3 pages in my test code, but if i use 'pdf.number_pages "/", [doc.pdf.margin_box.right, 0]' then the third page's content will cover the second page's content.

2. And another problem, I don't know how to fix, I tried many way but this problem still there,
   so I think may it's a bug. Please check the PDF file in Attachment, you can see there are half page white space in the second page, I tried to remove it and let the content on third page move the second page, but failed. If I remove the big table, the big white space gone. You can find my source code in attachment. please help to fix it.
