AWI commit of patch from Joseph Wang <joequant@gmail.com> followed by styling.  Move transform and clipping information into the text element itself.  This makes the resulting files more compact. For plots with a lot of text (e.g., symbol plots) this can save up to a factor of two in the resulting size.

Tested by: Alan W. Irwin <airwin@users.sourceforge.net> using the
test_c_svg target (which showed no obvious errors) and visually
comparing results between the old svg code and the current code.
