Summary: patch for simplified horizontal positional tracking

Initial Comment:
1. simpler calculations for horizontal position update
when inside []TJ arrays, now by pure additions within a
fontsize/10000 raster; no rounding errors can
accumulate. Gives about 7 % pdftex speed gain when
typesetting fiction-type stuff.

2. writet3.c now also with standard /FontMatrix [0.001
0 0 0.001 0 0], tidied up a little (.pgc part
untested). No need anymore (hope it's right) to handle
PK fonts specially by adv_char_width() in pdftex.web.

3. wrong use of printf() at a few places corrected by
Martin.

Work in progess, not safe for production. Needs more
testing, particularly with PK fonts.

Regards, Hartmut
