WERD::bounding_box

Return the bounding box of the WERD. This is quite a mess to compute! ORIGINALLY, REJECT CBLOBS WERE EXCLUDED, however, this led to bugs when the words on the row were re-sorted. The original words were built with reject blobs included. The FUZZY SPACE flags were set accordingly. If ALL the blobs in a word are rejected the BB for the word is NULL, causing the sort to screw up, leading to the erroneous possibility of the first word in a row being marked as FUZZY space.

This method returns a new werd constructed using the blobs in the input all_blobs list, which correspond to the blobs in this werd object. The blobs used to construct the new word are consumed and removed from the input all_blobs list. Returns NULL if the word couldn't be constructed.
