The current CVS can handle many PSTricks specials but not these. From 
what I can see, the code attempts to put TeX glyphs at a given 
coordinate by enclosing them with PSTricks specials:

@364 DRAW CMD:  XXX1 61 'ps: address@hidden begin { 56.90549 56.90549 } PutCoor 
PutBegin  end'
@427 DRAW CMD:  PUSH
@428 DRAW CMD:  PUSH
@429 DRAW CMD:  DOWN3 235560
@433 DRAW CMD:  PUSH
@434 DRAW CMD:  RIGHT3 -592745
@438 DRAW CMD:  FNT_DEF1 39 104037337 717619 655360 0 6 'ptmr7t'
@460 DRAW CMD:  FONT_39
@461 DRAW CMD:  SETC_084
  VF CHAR:      'T' 84 at (102,321) tfmw 438464
@462 DRAW CMD:  RIGHT3 -50230

@468 DRAW CMD:  SETC_116
  VF CHAR:      't' 116 at (123,321) tfmw 199491
@469 DRAW CMD:  POP
@470 DRAW CMD:  POP
@471 DRAW CMD:  POP
@472 DRAW CMD:  XXX1 30 'ps: address@hidden begin  PutEnd  end'

This will, quite frankly, not work in dvipng until I implement PutBegin 
and PutEnd natively (or give the whole thing to dvips...). I am not 
going to spend time doing that for every special that PSTricks or 
TIKZ/PGF (or whatever) come up with, there are simply too many.

The alternative is to include a native PostScript interpreter. Volunteers?
