Summary: Character positioning patch

Initial Comment:
Experimental patch increases resolution of /Widths
array by 1 fractional digit, makes corrections of type
")-1(" and ")1(" in the TJ array happen much less
often, particularily for CM fonts. Gives e. g. 1 % PDF
file size shrink for pdfetex web sources compiled into PDF.

Rough patch only, not for production. Testing welcome.

Regards, Hartmut

Patch extended: Now pdf_set_origin has (h, v) parameters,
simplifies pdf_begin_text procedure.

Removed pdf_first_space_corr variable, as it seems that it
was defunct anyway: There was no pdf_end_string procedure
call (only place where something is done with
pdf_first_space_corr), where afterwards the pdf_h variable
(then modified by pdf_first_space_corr) would actually be
used. E. g. pdf_moveto uses pdf_last_h instead, and after
pdf_end_text there is anyway a pdf_set_origin call.

And pdf_begin_string gets simpler.

Testing welcome!

patch updated: now the TJ array building in procedure
pdf_begin_string is simplified/tidied up.

Testing welcome!
