bitblt routines:

PDF routines:
[Page numbers refer to _Portable Document Format Reference Manual_ by
Adobe Systems Incorporated, Addison-Wesley, 1993.]
* G4 fax encoding
* proper output of real numbers - variable precision, no exponent
* bookmarks (outline)
* name trees, number trees
* page labels
* balance pages tree - currently a degenerate single-level tree, but the
PDF spec recommends max. of 6 children per parent
* ImageMask (p. 79) using fill color (g, k, or rg operator, p. 95)
* thumbnails
* PDF Page rotate attribute (p. 53)?
* fix array element ordering
* memory management - need to reference count all structures and free
them as appropriate - not necessary for t2p program
* when an object is written to the file, set a flag to indicate that
it is now immutable
* buffered streams (vs. current callback mechanism for unbuffered streams)
* add support for streams with multiple filters
