ignore form dictionaries that do not contain fields #131
...
though a form dictionary should always contain fields (as required by the spec) it is possible for this entry to be missing. in this case we return false for trygetform.

though required by the spec an adobe type 1 font may be missing all width data. in this case we default to empty values and treat it like a normal adobe type 1 font.

move values back to computed properties
...
the additional stored fields made the struct slower to copy and had an impact on the performance. this moves non-essential fields back to computed properties.

make width, height, area, rotation and centroid lazy
...
since the rectangle constructor is a hot path any calculations slow the library down considerably. for this reason we move calculations for the following properties into the property getter:
* width (cached)
* height (cached)
* rotation
* area
* centroid
where values are cached they set their backing field once calculated. this won't be thread safe if the same rectangle is accessed on multiple threads.

fix usages of rectangle constructor.
...
now that rectangle constructor uses the order [ llx, lly, urx, ury ] and does not apply correction for points constructor parameters must be passed in the correct order. this change fixes the hyperlink factory which was passing them in the wrong order.
in addition the pdfpath bounding box was using left, right, top and bottom to calculate the minimum bounding box. this produced incorrect values now individual path operator bounding boxes are rotated, since for a rotated rectangle top may be less than bottom.
the performance seems to have taken a hit due to these changes however.
