Latex with pstricks saves incorrect dimension values

[Karadomos]

When saving a document in .tex with pstricks and comping it afterwards with a latexcompiler, the resulting objects are of incorrect sizes.

Two Reasons:
1) the pstrick macros contain the line:
\psset{xunit=.5pt,yunit=.5pt,runit=.5pt}
However, the graphic's values are not doubled
2) The saved dimensions of the objects are the pixel sizes not the pt sizes.

Narrowed down to example:
(tried on windows xp, with inkscape 0.46 on A4 paper )
- create a square of size 5cmx5cm and saving it as .tex
- resulting tex file contains the picture dimensions: \begin{pspicture}(744.09448242,1052.36218262), which are the px-values and shoud be the pt-values (595.28,841.89) or doubled if considering 1).
- the dimensions of the square are incorrect in the same manner

Same thing with inkscape 0.46 on ubuntu 8.04

[Carlos Marcelo de Oliveira Stein (carlos-stein)]

Same thing here.
Inkscape 0.48 windows

And it affects other drawings placed after the inclusion of the tex file.

I have to use:

\input{name_of_tex_file} %file saved in inkscape
\psset{unit=1cm}
