Revision 2443

	* Doc/technotes/coding_guidelines.txt: easy typo fixed.

	* Extensions/svgexport/test/test_svgmapwriter.py:
	Removed test_drawbezier in favour of new test_drawspline3 and
	test_drawspline4 within new class TestDrawSplines(TestVirtualDC).
	All only to test DrawSpline.

	* Extensions/svgexport/svgmapwriter.py(DrawSpline):
	New implementation now really using the strange algorithm of
	xfig 3.1's approximated splines and its conversion to postscript
	with one twist: SVG can do quadratic beziers, so skipped translation
	to cubic beziers.
	(TestWithDC): Typo in comment fixed.
