Acid3 Test Failures of KHTML

This is an overview of the remaing failures of KHTML on the Acid3 test. FF3.1 beta2pre scores 92/100, with 4 of the 6 colored boxes filled in correctly.

Test No	Area	Diagnosis	Comment	passes in FF3	passes in FF3.1
04	HTML Parser	Parser bug: iframe missing text kid	discard_until = ID_IFRAME+ID_CLOSE_TAG --- added in http://lists.kde.org/?l=kde-commits&m=99906936412933&w=2.	No	Yes
13	DOM Range	Unhandled mutation		Yes	Yes
26/27	JS + DOM Memory management	Cycle breaking cleaning up too much		Yes, but slow	Yes, but slow
29	HTML Parser	Parser bug: table missing whitespace kid		Yes	Yes
44	CSS Parser	Misparse of html*.test selector (see below)		Yes	Yes
48 (red linktest failed)	CSS	:visited doesn't match URL of part	Bug in konqueror's history manager. Works in testkhtml	Yes	Yes
51	DOM2 Table	Stray row	Buggy test. Raised with Ian Hickson.	Yes	Yes
53	DOM2 Forms	Not managing form's element collection when not in document.		Yes	Yes
70	XML Parser	" UTF-8 encoded XML document with invalid character did not have a well-formedness error"		No
74	DOM	"getSVGDocument missing on <iframe> element."		Yes
75	SVG+SMIL DOM	"SVG DOM interface SVGRectElement not supported."		No
76	SVG+SMIL DOM	??		No
77,78,79	SVG Fonts	??		No

Note: An upgrade to PCRE 7.7 is required to make tests 89 and 90 pass.

Random patch storage

These are not meant for commit, but more as a proof of analysis, and starting point for proper fix:

#16, red cat.

Ugly, but roughly correct.
