Hi,

I added a new primitive to fetch the BBox of a pdf image.

- extensions for pdf inclusion:
    - added \pdfpagebox as the default setting for pagebox specification. Value
      specified to individual use of \pdfximage will override this setting. When
      set to 0 CropBox will be used as default.
      
      Example:
,--------
|       \pdfpagebox=1                 % use MediaBox as default
|       \pdfximage {f.pdf}            % use MediaBox
|       \pdfximage cropbox {f2.pdf}   % use CropBox
`--------


    - added \pdfximagebbox to fetch the BBox of a pdf image. The BBox is taken
      from the pagebox associated with the image.

      Example:
,--------
|       \pdfximage {f.pdf}  % CropBox will be use by default
|       \dimen1=\pdfximagebbox\pdflastximage 1    % fetch x1 from CropBox
|       \dimen2=\pdfximagebbox\pdflastximage 2    % fetch y1 from CropBox
|       \dimen3=\pdfximagebbox\pdflastximage 3    % fetch x2 from CropBox
|       \dimen4=\pdfximagebbox\pdflastximage 4    % fetch y2 from CropBox
