POV 3.5 b 12 for Win

10.1.5  Transformations

  From the syntax looks like following:
    transform{inverse}
  is possible and yes - it is possible - it is inversion of
    transform{}
  and it is also possible but this case is not included in syntax of quickref.

10.1.6  Camera

  Below lines are correct with quick ref but returns parse error
    #local C=camera {};
    camera{ orthographic C }
    camera{ C C }
  It is becouse CAMERA_IDENTIFIER as applied at begining of both CAMERA_ITEMS
  and CAMERA_MODIFIERS. I think it should be first optional element of pure
  camera statement:
  CAMERA:
    camera {[CAMERA_IDENTIFIER][CAMERA_TYPE][CAMERA_ITEMS][CAMERA_MODIFIERS]}

Curious.  Simple enough.  I placed square brackets around TRANSFORM_ITEM... inside the
transform statement.

Another carryover from my version 3.1g doc.  It was probably wrong there, too!  I
moved [CAMERA_IDENTIFIER] out of the items
and modifiers and into the camera statement as suggested.
