Extend the Arlington PDF model for content stream operators and operands, according to ISO 32000-2:2020.

Things to check for:

  • correct number, type and range of operands for each operator
  • correctly balanced and nesting of operator pairs: q/Q, BX/EX, BT/ET, BMC/BDC/EMC
  • ensuring a "current point" for vector drawing
  • ensuring d0/d1 are always the first operand
  • ensuring coloured vs uncoloured operators for certain kinds of content streams
  • unknown operators outside of BX/EX

This should also be done for the DA entry of annotation dictionaries and field dictionaries.

...and the DA entry of AcroForm.
