\pdfpxdimen primitive patch
This is a Web patch file for pdfetex.
The change file for pdfetex does two things:
\pdpxdimen obeys grouping and (at the moment) it does not become
'fixed', you can change the value during the TeX run as often as you
like. Dimensions using "px" are converted to "sp" units right after an
actual assignment has been done, of course.
- It allows a new dimension specification keyword: "px", similar to
"ex" and "em", but using the new internal counter "pdf_px_dimen"
instead of the current font.
- It defines the new primitive \pdfpxdimen, to set this internal counter
(the value is the number of scaled points in one px, default is set
by initex to be: 1px = 1pt = 65536sp).
