Landing of SVG_20020806_BRANCH, Bug 182533. Refactoring of SVG backend, new GDI+ and Libart rendering
backends, text support on Windows (GDI+), rudimentary text support on Linux (libart/freetype2), presentation
attributes, lots of bug fixes (see bug 182533 for dependency list).
Not part of default build; code is #ifdef'ed out.
r=sicking, sr=jst for dom and htmlparser changes
r=bsmedberg, sr=tor for config changes
r=dbaron, sr=bzbarsky for content and layout changes
r=tor, sr=bzbarsky for gfx changes
